Sun Java System Messaging Server 6.3 Beta 版 |
Messaging Server 是一个高性能、高安全性的邮件传送平台,可以通过扩展为成千上万的用户服务。Messaging Server 提供了强大的安全功能,通过用户验证、会话加密以及适当的防垃圾邮件和病毒的内容过滤来确保邮件传送的完整性。使用 Messaging Server,企业和服务提供商可以为整个员工、合作伙伴和客户群体提供安全、可靠的邮件传送服务。
通过使用开放的 Internet 标准,Messaging Server 提供了强大、灵活的解决方案来满足各种规模企业和邮件传送主机对于电子邮件的需要。
Messaging Server 6.3 发行版中添加了以下新功能和增强功能:
Messaging Server 通过 Sun Content Management 以及 Sun Compliance and Content Management Solution 支持归档功能。邮件归档系统会将全部或部分(指定子集的)收到的邮件和外发的邮件保存在 Messaging Server 以外的系统上。已发送、接收、删除和移动的邮件都可以在归档系统中进行保存和检索。电子邮件用户无法对已归档的邮件进行删除或修改,因此传入和传出通信的完整性得到了维护。邮件归档对于规范记录的保存、邮件存储库管理和邮件备份十分有用。有关详细信息,请参见《Message Archiving Using the Sun Compliance and Content Management Solution》。
尽管对可操作的归档进行了记录,但此功能直到 Sun Java System Messaging Server 6.3 Patch 1 发行时才启用。
Webmail 服务器也称为 mshttpd(Messaging Server HTTP 守护进程),可以为 Messenger Express 和 Communications Express 客户端提供电子邮件服务。现在,Webmail 服务器通过 IMAP 服务器访问邮件存储库。此功能提供了很多优点:
Messenger Express 和 Communications Express 客户端现在可以访问位于不同后端邮件存储库上的共享文件夹。
不必在每个后端服务器上安装 Webmail 服务器。
Webmail 服务器可以用作前端服务器,执行以前由 Messenger Express Multiplexor (MEM) 执行的多路复用功能。
不再使用 MEM。请参见Messaging Server 中已过时和已删除的功能。
对于客户端,除了用户现在可以访问不在其邮件存储库上的共享文件夹之外,没有发生任何更改。在早期版本中,MEM 接收 HTTP 客户端请求,并将其转发到相应后端邮件存储库上的相应 Webmail 服务器。因此,必须在每个后端服务器上安装 mshttpd 的副本。现在,Webmail 服务器可以作为前端服务器,以接收 HTTP 客户端电子邮件请求。它可以将这些请求转换为 SMTP 或 IMAP 调用,并将这些调用转发给 MTA 或后端邮件存储库上的相应 IMAP 服务器。
MeterMaid 通过确定 IP 地址最近何时连接过于频繁并应暂停使用来发挥限制功能。MeterMaid 如同巡视街道的警员,负责查找超过分配量的 IP 地址。它是一个可以取代 conn_throttle.so 的系统信息库进程,提供了类似功能,但却将其扩展到 Messaging Server 产品。此外,MeterMaid 比 conn_throttle.so 具有更高的可配置性。
目前不会针对 conn_throttle.so 提供进一步的增强功能。
Messaging Server 支持使用常见且可免费获取的第三方病毒扫描程序 ClamAV,以检测邮件是否感染了病毒和特洛伊木马。
现在可以在 Messaging Server 中运行基于 Sendmail Content Management API 的程序,该程序也称为 Milter(邮件过滤器 Mail Filter 的缩写)。Milter 为第三方软件提供插件接口,以便在邮件通过 MTA 传递时对其进行验证和修改。Milter 可以处理邮件的连接 (IP) 信息、信封协议元素、邮件标题和/或邮件正文内容,并且可以修改邮件的收件人、标题和正文。在垃圾邮件拒绝、病毒过滤和内容控制等过程中可能会用到过滤器。通常,Milter 尝试以可伸缩的方式来解决站点范围内的过滤问题。请参见《Sun Java System Messaging Server 6.3 管理指南》中的“使用 Milter”。
IMAP SORT
对 IMAP 协议的 SORT 扩展提供了一种基于服务器来对邮件进行排序的方式,不需要客户端自身去下载完成此操作所必需的数据。请参见 http://www.ietf.org/internet-drafts/draft-ietf-imapext-sort-18.txt 以获取详细信息。
IMAP COMPARATOR
IMAP IDLE
对 IMAP 规范的 IMAP IDLE 扩展(已在 RFC 2177 中定义)允许 IMAP 服务器在新邮件到达用户邮箱或用户邮箱中发生其他更新时通知邮件客户端。IMAP IDLE 功能具有以下优点:
邮件客户端无需轮询 IMAP 服务器以查找收到的邮件。
取消客户端轮询可降低 IMAP 服务器上的工作负载,并会提高服务器性能。当用户收到少量邮件或未收到邮件时,客户端轮询是最浪费的;客户端会继续以配置的时间间隔进行轮询(通常是每 5 分钟或每 10 分钟轮询一次)。
邮件客户端向用户显示新邮件的时间更接近于该邮件到达用户邮箱的实际时间。邮件状态更改也会以接近实时的方式显示出来。
IMAP 服务器无需等待下一个 IMAP 轮询邮件即可向客户端发出有关新邮件或更新邮件的通知。只要有新的邮件到达或邮件状态发生更改,IMAP 服务器就会收到通知。然后,该服务器会通过 IMAP 协议通知客户端。
默认情况下,IMAP IDLE 处于关闭状态。
高性能用户查找和验证 (High Performance User Lookup and Authentication, HULA) 为 Communications Suite 提供了一个库,以便实现一致的用户查找语义(例如,domainmap 对域查找所起的作用)。使用 HULA 时,以下接口更改将会影响 MMP:
已在多个发行版中实现 HULA。此发行版支持 HULA 的 MMP 实现。下一个发行版支持邮件存储库和 MTA 中的 HULA 实现。
以下接口更改将会影响 MMP:
MMP 现在支持用户状态属性。在此发行版之前,MMP 依赖于后端服务器来强制用户状态。此更改可减少用户迁移方案中的后端负载。
MMP 日志邮件已标准化为始终包含一个整数连接 ID,在 MMP 进程生存期内不会重复使用该 ID。以前,MMP 邮件使用可重复使用的十六进制连接环境地址。另外,lpool 层使用难以关联的不同环境地址。现在,MMP、hula 和 lpool 层都将使用同一 ID。
MMP 调试日志级别配置设置现在使用系统日志模式的日志级别,而不是未指定的数字级别。LogLevel 选项以前默认为 1;现在默认为 5 (LOG_NOTICE)。3 以下的值不会产生任何输出。介于 3 (LOG_ERR) 和 7 (LOG_DEBUG) 之间的值可以在调试日志中提供不同的输出量。
MMP 现在支持 option.dat 中的其他 MTA 选项,如下所示:LDAP_DOMAIN_FILTER_SCHEMA1、LDAP_DOMAIN_FILTER_SCHEMA2、LDAP_ATTR_DOMAIN1_SCHEMA2、LDAP_ATTR_DOMAIN2_SCHEMA2、LDAP_ATTR_DOMAIN_SEARCH_FILTER、LDAP_DOMAIN_ATTR_BASEDN、LDAP_DOMAIN_ATTR_CANONICAL、LDAP_DOMAIN_ATTR_ALIAS、LDAP_UID、LDAP_DOMAIN_ATTR_UID_SEPARATOR、LDAP_DOMAIN_ATTR_STATUS、LDAP_DOMAIN_ATTR_MAIL_STATUS、LDAP_USER_STATUS、LDAP_USER_MAIL_STATUS。
在早期的发行版中已实现了 TCP 访问过滤器中的 ident 支持,但未经过测试。手册中已包含了相应的警告,表明 ident 支持在几个发行版之前就已过时。新的代码无法实现 ident 支持。需要 ident 的过滤器将导致验证失败,并显示错误消息。
早期版本的 MMP 允许使用包含任何 UTF-8 字符的用户名,但未经过测试。HULA 将强制使用正确的 UTF-8 语法,并禁止过长的编码和替代项。
imsconnutil 实用程序的新 -k 选项用于断开用户与 IMAP 和 POP 会话的连接。登录到 Communications Express 的用户将丢失基本的 IMAP 连接,因此也会断开连接。
JMQ 通知插件允许您使用 Java Messaging Service (JMS) 标准发送通知邮件。现在,您可以将插件配置为向两种不同的邮件传送服务发送通知:
Sun Java System Message Queue 3.6 或更高版本(实现 JMS 标准)
事件通知服务
使用 Message Queue,可以为邮件或队列生成主题,或者同时为这两种传送方法生成主题。Message Queue 还提供了增强的负载平衡、可伸缩性和可靠性。请参见《Sun Java System Messaging Server 6.3 管理指南》中的第 22 章 “配置 JMQ 通知插件为 Message Queue 生成邮件”。
发件人策略框架 (Sender Policy Framework, SPF) 是一种技术,可以在 SMTP 对话期间检测和拒绝伪造的电子邮件。具体来说,SPF 是一种方法,它允许域对可能使用其域名的主机进行明确授权。此外,可以将接收主机配置为检查此授权。这样,SPF 可以显著减少伪造电子邮件的实例。请参见 《Sun Java System Messaging Server 6.3 管理指南》中的第 15 章 “使用发件人策略框架处理伪造的电子邮件”。
现在可以为特定的文件夹和邮件类型设置邮件存储库配额。邮件类型配额允许您指定邮件类型(如语音邮件和电子邮件)的限制。文件夹配额可以对用户的文件夹大小设置限制(以字节或邮件数为单位)。例如,可以对“垃圾箱”文件夹设置配额。Messaging Server 允许您为域和用户设置默认配额以及自定义配额。请参见《Sun Java System Messaging Server 6.3 管理指南》中的“关于消息存储配额”。
无法再通过 Administration Console 获取证书。而应使用一个名为 msgcert 的新命令。仍然可以使用旧的 certutil 命令,但该命令更复杂,并且未经国际化。有关详细信息,请参见《Sun Java System Messaging Server 6.3 管理指南》中的“获得证书”。
有关 Sun JavaTM Enterprise System Monitoring Framework 的信息,请参见《Sun Java Enterprise System 5 Monitoring Guide》。
早期版本的 MMP 不会查看 inetUserStatus、 mailUserStatus、inetDomainStatus 和 mailDomainStatus 属性。如果帐户处于非活动、已禁用或已删除状态,则 MMP 依赖于后端服务器才能拒绝连接。现在,当前版本的 MMP 支持这些属性,并且当状态不是“活动”、“超过配额”或为空时在 MMP 层终止连接。这样可以在迁移用户时提高部署的可伸缩性。
MMP 调试日志级别和会话 ID:MMP 的 "LogLevel" 配置选项的含义已发生更改,以便遵循系统日志约定。在早期的发行版中, 该选项是一个任意值,默认为 1。在此发行版中,它将遵循系统日志约定。默认值为 5 (LOG_NOTICE),介于 3 (LOG_ERR) 和 7 (LOG_DEBUG) 之间的值将更改所显示的邮件集,并且含义与其对 syslog() 的含义相同。此外,MMP 调试日志文件中的邮件现在使用会话/连接 ID,该 ID 以数字表示,并且在 MMP 进程生存期内是唯一的。
本部分介绍的许多 MAT 新功能都合并到 Messaging Server 文档中了。这里列出这些功能是为了文档的完整并发布新增功能。
(54) A new facility has been added to store information that previously would have gone in the general, forward, and reverse databases in the compiled configuration instead. A new MTA option, USE_TEXT_DATABASES, has been added to control this capability. This option is bit encoded. If bit 0 (value 1) is set the file IMTA_TABLE:general.txt is read as the MTA configuration is initialized and the information from that file replaces all uses of the general database. If bit 1 (value 2) is set the file IMTA_TABLE:reverse.txt is read and used in instead of the reverse database. Finally, if bit 2 (value 4) is set the file IMTA_TABLE:forward.txt is read and used instead of the forward database. The default value for this option is 0, which disables all use of text databases. Note that use of the text database option means that changes to the underlying files will only be seen after a cnbuild, and in the case of running processes, after a reload. Several additional MTA options can be used to set the initial size of the various text database tables: GENERAL_DATA_SIZE - Initial number of entries in the general text database. REVERSE_DATA_SIZE - Initial number of entries in the reverse text database. FORWARD_DATA_SIZE - Initial number of entries in the forward text database. The MTA stores the database template strings in string pool 3, so the STRING_POOL_SIZE_3 MTA option controls the initial allocation of space for this purpose. Note that these various options only control initial sizes; the various tables and arrays will resize automatically up to the maximum allowed size. The maximum string pool size in 6.2P8 and earlier is 10Mb, after 6.2P8 is has been increased to 50Mb. Up to 1 million entries are allowed in 6.2P8 and earlier, this has been increased to 2 million entries in later releases. (144) A new MTA option, USE_CANONICAL_RETURN, has been added. This option is bit-encoded with the various bits matching those of the USE_ORIG_RETURN option. Each place where the MTA performs a comparison operation against the envelope from (MAIL FROM) address has an assigned bit. If the bit in USE_CANONICAL_RETURN is clear normal rewriting is applied to the envelope from address prior to use. In particular rewriting from mailAlternateAddress attributes to mail attributes will be performed; mailEqvuialentAddress attributes won't be rewritten to the corresponding mail attribute. If, however, the bit is set, the corresponding address will be rewritten if it appears in a mailEquivalentAddress attribute. It should be noted that the bit USE_ORIG_RETURN will, if set, disable rewriting entirely. So setting a bit in USE_ORIG_RETURN makes the corresponding bit in USE_CANONICAL_RETURN a noop. Note that the various bits of USE_ORIG_RETURN don't appear to be documented at this time, so here's a list of them: Bit Value Usage 0 1 When set, use the original envelope From: address in ORIG_SEND_ACCESS mapping table probes 1 2 When set, use the original envelope From: address in SEND_ACCESS mapping table probes 2 4 When set, use the original envelope From: address in ORIG_MAIL_ACCESS mapping table probes 3 8 When set, use the original envelope From: address in MAIL_ACCESS mapping table probes 4 16 When set, use the original envelope From: address in mailing list [AUTH_LIST], [MODERATOR_LIST], [SASL_AUTH_LIST], and [SASL_MODERATOR_LIST] checks 5 32 When set, use the original envelope From: address in mailing list [CANT_LIST] and [SASL_CANT_LIST] checks 6 64 When set, use the original envelope From: address in mailing list [AUTH_MAPPING], [MODERATOR_MAPPING], [SASL_AUTH_MAPPING], and [SASL_MODERATOR_MAPPING] checks 7 128 When set, use the original envelope From: address in mailing list [CANT_MAPPING] and [SASL_CANT_MAPPING] checks 8 256 When set, use the original envelope From: address in mailing list [ORIGINATOR_REPLY] comparisons 9 512 When set, use the original envelope From: address in mailing list [DEFERRED_LIST], [DIRECT_LIST], [HOLD_LIST], and [NOHOLD_LIST] checks 10 1024 When set, use the original envelope From: address in mailing list [DEFERRED_MAPPING], [DIRECT_MAPPING], [HOLD_MAPPINGS], and [NOHOLD_MAPPING] checks 11 2048 When set, use the original envelope From: address in mailing list checks for whether the sender is the list moderator 12 4096 When set, use the original envelope From: address in mailing list LDAP_AUTH_DOMAIN LDAP attribute (e.g., mgrpAllowedDomain) checks 13 8192 When set, use the original envelope From: address in mailing list LDAP_CANT_DOMAIN LDAP attribute (e.g., mgrpDisallowedDomain) checks 14 16384 When set, use the original envelope From: address in mailing list LDAP_AUTH_URL LDAP attribute (e.g., mgrpAllowedBroadcaster) checks 15 32768 When set, use the original envelope From: address in mailing list LDAP_CANT_URL LDAP attribute (e.g., mgrpDisallowedBroadcaster) checks 16 65536 OBSOLETE. In Messaging Server 5.0 and Messaging Server 5.1, when set use the original envelope From: address in mailing list LDAP_MODERATOR_RFC822 comparisons; since as of Messaging Server 5.2 there is no longer any such global MTA option nor need for such an attribute (since the LDAP_MODERATOR_URL attribute value can, in fact, specify a mailto: URL pointing to an RFC 822 address), this bit no longer has any meaning. 17 131072 When set, use the original envelope From: address in mailing list LDAP_MODERATOR_URL LDAP attribute (e.g., mgrpModerator) comparisons 18 262144 When set, use the original envelope From: address in any source-specific FORWARD mapping tables probes 19 524288 When set, use the original envelope From: address in any source-specific FORWARD database probes Bit 0 is the least significant bit. (145) The SPAMFILTERn_OPTIONAL MTA options now accept two additional values: -2 and 2. -2 and 2 are the same as 0 and 1 respectively except that they also cause a syslog message to be sent in the event of a problem reported by the spam filter plugin. (146) Old-style mailing lists defined in the aliases file or aliases database now accept a nonpositional [capture] parameter. If used the [capture] parameter specifies a capture address with the same semantics as capture addresses specified by the LDAP_CAPTURE attribute applied to a user or group in LDAP. (147) The default value for the MISSING_RECIPIENT_POLICY MTA option has been changed from 2 (add envelope recipient list as a To: field) to 1 (ignore missing recipient condition). This brings Messaging Server in line with what RFC 2822 recommends. (148) Although it will rarely make sense to do so, the x_env_to keyword can now be used without also setting single on a channel. (149) The MTA now has the ability to process multiple different LDAP attributes with the same semantics. Note that this is not the same as processing of multiple values for the same attribute, which has always been supported. The handling attributes receive depends on the semantics of the attribute. The possible options are: (a) Multiple different attributes don't make sense and render the user entry invalid. In 6.2 and later this handling is the default for all attributes unless otherwise specified. (b) If multiple different attribute are specified one is chosen at random and used. LDAP_AUTOREPLY_SUBJECT, LDAP_AUTOREPLY_TEXT, and LDAP_AUTOREPLY_TEXT_INT all receive this handling in 6.2 only; in 6.3 and later they receive the handling described in item 153 below. 6.3 adds the LDAP_SPARE_3 and LDAP_PERSONAL_NAME attribute to this category. Note that this was how all attributes were handled prior to 6.2. (c) Multiple different attributes do make sense and should all be acted on. This handling is currently in effect for LDAP_CAPTURE, LDAP_ALIAS_ADDRESSES, LDAP_EQUIVALENCE_ADDRESSES and LDAP_DETOURHOST_OPTIN. Note that LDAP_DETOURHOST_OPTIN attribute was first added to Messaging Server in 6.3. (150) The MTA now has the ability to chose between multiple LDAP attributes and attribute values with different language tags and determine the correct value to use. The language tags in effect are compared against the preferred language information associated with the envelope from address. Currently the only attributes receiving this treatment are LDAP_AUTOREPLY_SUBJECT (normally mailAutoReplySubject), LDAP_AUTOREPLY_TEXT (normally mailAutoReplyText), LDAP_AUTOREPLY_TEXT_INT (normally mailAutoReplyTextInternal), LDAP_SPARE_4, LDAP_SPARE_5, LDAP_PREFIX_TEXT and LDAP_SUFFIX_TEXT. It is expected that each attribute value will have a different language tag value; if different values have the same tag value the choice between them will be essentially random. 151) The length of URLs that can be specified in a mapping URL lookup has been increased from 256 to 1024. The same increase also applies to expressions evaluated by mappings and mapping calls to other mappings. (152) A new MTA option, LOG_REASON, controls storage of error reason information in log records. Setting the option to 1 enables this storage, 0 (the default) disables it. This information, if present, appears just before diagnostic information in log records. (153) A :percent argument has been added to spamtest. If present it changes the range of the spamtest result from 0-10 to 0-100. See the Internet Draft draft-ietf-sieve-spamtestbis-05.txt for additional information on this change. (154) The SpamAssassin spam filter plugin's DEBUG option setting now accepts an integer value instead of a boolean 0 or 1. The larger the value the more debugging will be generated. In particular, a setting of 2 or greater reports exactly what was received from spamd. (155) The conversion mapping now allows a new "PREPROCESS" directive. If specified it allows charset conversions to be done on messages prior to sending them to the conversion channel. (156) The $. metacharacter sequence can now be used in a mapping or rewrite rule to establish a string which will be processed as the mapping entry result in the event of a temporary LDAP lookup failure. By default temporary LDAP failures cause the current mapping entry to fail. This is problematic in cases where different actions need to be taken depending on whether the LDAP lookup failed to find anything versus the directory server being unavailable or misconfigured. The temporary failure string is terminated by an unescaped ".". In the case of mappings once a failure string has been set using this construct it will remain set until current mapping processing is completed. Rewrite rules behave differently; a temporary failure string remains set only for the duration of the current rule. "$.." can be used to return to the default state where no temporary failure string is set and temporary LDAP failures cause mapping entry or rewrite rule failure. Note that all errors other than failure to match an entry in the directory are considered to be temporary errors; in general it isn't possible to distinguish between errors caused by incorrect LDAP URLs and errors caused by directory server configuration problems. (157) Setting the LOG_FORMAT MTA option to 4 now causes log entries to be written in an XML-compatible format. Entry log entry appears as a single XML element containing multiple attributes and no subelements. Three elements are currently defined, en for enqueue/dequeue entries, co for connection entries, and he for header entries. Enqueue/dequeue (en) elements can have the following attributes: ts - time stamp (always present) no - node name (present if LOG_NODE=1) pi - process id (present if LOG_PROCESS=1) sc - source channel (always present) dc - destination channel (always present) ac - action (always present) sz - size (always present) so - source address (always present) od - original destination address (always present) de - destination address (always present) de - destination address (always present) rf - recipient flags (present if LOG_NOTARY=1) fi - filename (present if LOG_FILENAME=1) ei - envelope id (present if LOG_ENVELOPE_ID=1) mi - message id (present if LOG_MESSAGE_ID=1) us - username (present if LOG_USERNAME=1) ss - source system (present if bit 0 of LOG_CONNECTION is set and source system information is available) se - sensitivity (present if LOG_SENSITIVITY=1) pr - priority (present if LOG_PRIORITY=1) in - intermediate address (present if LOG_INTERMEDIATE=1) ia - initial address (present if bit 0 of LOG_INTERMEDIATE is set and intermediate address information is available) fl - filter (present if LOG_FILTER=1 and filter information is available) re - reason (present if LOG_REASON=1 and reason string is set) di - diagnostic (present if diagnostic info available) tr - transport information (present if bit 5 of LOG_CONNECTION is set and transport information is available) ap - application information (present if bit 6 of LOG_CONNECTION is set and application information is available) Here is a sample en entry: en ts="2004-12-08T00:40:26.70" pi="0d3730.10.43" sc="tcp_local" dc="l" ac="E" sz="12" so="info-E8944AE8D033CB92C2241E@whittlesong.com" od="rfc822;ned+2Bcharsets@mauve.sun.com" de="ned+charsets@mauve.sun.com" rf="22" fi="/path/ZZ01LI4XPX0DTM00IKA8.00" ei="01LI4XPQR2EU00IKA8@mauve.sun.com" mi="<11a3b401c4dd01$7c1c1ee0$1906fad0@elara>" us="" ss="elara.whittlesong.com ([208.250.6.25])" in="ned+charsets@mauve.sun.com" ia="ietf-charsets@innosoft.com" fl="spamfilter1:rvLiXh158xWdQKa9iJ0d7Q==, addheader, keep" Here is a sample co entry: co ts="2004-12-08T00:38:28.41" pi="1074b3.61.281" sc="tcp_local" dr="+" ac="O" tr="TCP|209.55.107.55|25|209.55.107.104|33469" ap="SMTP"/ Header (he) entries have the following attributes: ts - time stamp (always present, also used in en entries) no - node name (present if LOG_NODE=1, also used in en entries) pi - process id (present if LOG_PROCESS=1, also used in en entries) va - header line value (always present) Here is a sample he entry: he ts="2004-12-08T00:38:31.41" pi="1074b3.61.281" va="Subject: foo"/ (158b) Added list authorization policy values SMTP_AUTH_USED and AUTH_USED. These are similar in effect to the old SMTP_AUTH_REQUIRED and AUTH_REQ but unlike the old values do not require posters to authenticate. (159) Sieve errors are now logged as such in mail.log when LOG_FILTER is enabled. (160) The ALLOW_TRANSACTION_PER_SESSION limit kicked in one transaction too early; it now allows the specified number of transaction instead of one less. (161) The type of transport protocol in use (SMTP/ESMTP/LMTP) is now logged and made available to the various access mappings. In particular, two new modifier characters have been added to the set that can appear after an action indicator in the mail.log* files: E - An EHLO command was issued/accepted and therefore ESMTP was used L - LMTP was used Previously the only modifier characters that would appears were A (SASL authentication used) and S (TLS/SSL used). Additionally, the $E and $L flags respectively will be set as appropriate for the various *_ACCESS mappings. (162) Wildcards are now allowed in the strings used to match verdicts returned by spam filters. (163) imsimta encode now supports three new switches: -disposition=VALUE Sets the content-disposition to the specified VALUE -parameters=NAME=VALUE Specifies one or more additional content-type parameters and their values -dparameters=NAME=VALUE Specifies one or more additional content-disposition parameters and their values (164) Bit 4 (value 16) of the DOMAIN_UPLEVEL MTA option is now used to control whether address reversal rewriting is: (1) Skipped if the address is a mailEquivalentAddress (bit clear) (2) Performed only if the address is a mailAlternateAddress (bit set) (165) A value "/" given as an [envelope_from] nonpositional alias parameter, as an errors to positional alias parameter, or as a value of the mgrpErrorsTo LDAP attribute is now interpreted as a request to revert to using the original envelope from address for the incoming message while retaining mailing list semantics. This can be useful for setting up mailing lists that report all forms of list errors to the original sender. (166) The Job controller directory sweep is now more sophisticated. Instead of reading all the files in the queue directory in the order in which they are found, it reads several channel queue directories at once. This makes for much more reasonable behaviour on startup, restart, and after max_messages has been exceeded. The number of directories to be read at once is controlled by the job controller option Rebuild_Parallel_Channel. This can take any value between 1 and 100. The default is 12. (167) The sieve interpreter now keeps track of whether a response message was generated by a notify or vacation action and logs this information as needed. (168) Add the option Rebuild_In_Order parameter to the job_controller. If this is set to a non zero value, then on startup the job controller adds previously untried (ZZ*) messages to the delivery queue in creation order. Previous (and default) behavior is to add the messages in the order in which they are found on disk. There is a cost associated with recreating the queues in order. (169) Some additional reasons why a requested vacation response isn't sent are now logged. (170) Add the command imsimta cache -change command. This command allows certain job controller parameters to be changed on the fly. The allowed formats of this command are: imsimta cache -change -global -debug=<integer> imsimta cache -change -global -max_messages=<integer> imsimta cache -change -channel_template=<name> master_job=<command> imsimta cache -change -channel_template=<name> slave_job=<command> imsimta cache -change -channel=<name> master_job=<command> imsimta cache -change -channel=<name> slave_job=<command> imsimta cache -change -channel=<name> thread_depth=<integer> imsimta cache -change -channel=<name> job_limit=<integer> Changing parameters for a channel template (e.g. tcp_*) changes that parameter for all channels derived from that template. (171) Add the command imsimta qm jobs. This command displays what messages are being processed by what jobs for what channels. Typical output might be: channel <channel name> job <pid> host <host name> host <host name> <count of hosts> HOSTS BEING PROCESSED BY JOB <pid> message <subdir/message name> message <subdir/message name> processed messages: <# messages sucessfully dequeued> failed processing attempts: <# messages reenqueued> <count of messages> MESSAGES BEING PROCESSED BY JOB <pid> <count of jobs> JOBS ACTIVE FOR CHANNEL foo <count of active channels> ACTIVE CHANNELS In the past they were only available to the various *_ACCESS mappings. E - Incoming connection used ESMTP/EHLO. L - Incoming connection used LMTP/LHLO. F - NOTIFY=FAILURES active for this recipient. S - NOTIFY=SUCCESSES active for this recipient. D - NOTIFY=DELAYS active for this recipient. A - SASL used to authenticate connection. T - SSL/TLS used to secure connection. (174) The buffer used for spamfilter verdict destination strings has been increased in size from 256 to 1024 characters. This was done to accomodate the much longer verdict destination strings that Brightmail 6.0 can return. (175) Two new values now have meaning for the various SPAMFILTERx_OPTIONAL MTA options: 3 and 4. A value of 3 causes spamfilter failures to accept the message but queue it to the reprocess chanel for later processing. A value of 4 does the same thing but also logs the spam filter temporary failure to syslog. (176) The ability to log the amouint of time a message has spent in the queue has been added to the MTA logging facility. A new option, LOG_QUEUE_TIME, enables this capability. Setting the option to 1 enables queue time logging, while the default value of 0 disables it. The queue time is logged as an integer value in seconds. It appears immediately after the application information string in non-XML format logs. The attribute name in XML formatted logs for this value is "qt". (177) Source channel switching based on user or domain settings is now possible. There are three new settings involved: (a) A new channel keyword userswitchchannel. This keyword must be present on the initial source channel for user channel switching to occur. (b) A new MTA option LDAP_DOMAIN_ATTR_SOURCE_CHANNEL that specifies the name of a domain-level attribute containing the name of the channel to switch to. (c) A new MTA option LDAP_SOURCE_CHANNEL that specified is the name of a user-level attribute containing the name of the channel to switch to. Additionally, the channel being switched to must be set to allow channel switches, that is, it cannot be marked with the noswitchchannel keyword. Switching is done based on information returned by rewriting the MAIL FROM address. Note that MAIL FROM addresses are easily forged so this functionality should be used with extreme care. (178) List expansion in the context of the mgrpallowedbroadcaster LDAP attribute now includes all the attributes used to store email addresses (normally mail, mailAlternateAddress, and mailEquivalentAddress). Previously only mail attributes were returned, making it impossible to send to lists restricted to their own members using alternate addresses. (179) The default for the GROUP_DN_TEMPLATE MTA option has been changed to ""ldap:///$A??sub?mail=*". It used to be ""ldap:///$A?mail?sub?mail=*". This change makes the change described in item 178 work correctly in the case of lists defined using DNs. a domain-level attribute containing the default mailhost for the domain. If set and the attribute is present on the domain the mailhost attribute is no longer required on user entries in the domain. This option currently has no default, but preferredmailhost is the logical attribute to use as long as some other, conflicting usage doesn't exist. (181) New channel keywords generatemessagehash, keepmessagehash, and deletemessagehash. Generatemessage will, if specified on a destination channel, cause a Message-hash: header field to be inserted into the message. Keepmessagehash will cause any existing Message-hash: field to be retained. Deletemessagehash will delete any existing Message-hash: field. Deletemessagehash is the default. The value placed in Message-Hash: fields is (obviously) a hash of the message. Several new MTA options control how the hash is generated: MESSAGE_HASH_ALGORITHM - The hash algorithm. Can be any of "md2", "md4", "md5" (the default), "sha1", "md128" (for RIPE-MD128), or "md160" (for RIPE-MD160). MESSAGE_HASH_FIELDS - Comma separated list of fields from the header to hash (in order). Any known header field can be specified. If this option is not specified it defaults to "message-id,from,to,cc,bcc, resent-message-id,resent-from,resent-to,resent-cc,resent-bcc, subject,content-id,content-type,content-description". (182) New MTA option UNIQUE_ID_TEMPLATE. This option specifies a template used to convert an address into a unique identifier. The template's substitution vocabulary is the same as that for delivery options. The resulting unique identifier is intended for use by message archiving tools. (183) Per-user aliasdetourhost is now possible through the following set of features: (a) Added a aliasoptindetourhost channel keyword. This is similar in function to aliasdetourhost except detouring only occurs if the user has opted in via the following attribute. The keyword's value is a comma-separated list of potential detour hosts. (b) Added a LDAP_DETOURHOST_OPTIN MTA option, which specifies the name of an attribute used to opt the user in to the detour (assuming of course the source channel has aliasoptindetourhost set). If the values of this attribute contain periods they will be compared against the list of potential detour hosts and the first host on the list that matches will be the chosen detour. If the value doesn't contain a period the first detour host will be used unconditionally. (c) Added a ALIASDETOURHOST_NULL_OPTIN MTA option. This is similar to SPAMFILTERx_NULL_OPTIN - it specifies a "special" value which if used in the optin attribute is treated as the same as the attribute being omitted. The default valueis "", which means that an empty attribute value is ignored. (184) Support for a new IP_ACCESS table has been added. This access mapping is consulted during SMTP client operations just prior to attempting to open connections to a remote server. The mapping probe has the following format: source-channel|address-count|address-current|ip-current|hostname source-channel is the channel the message is being dequeued from, address-count is the total number of IP addresses for the remote server, address-current is the index of the current ip address being tried, ip-current is the current IP address, and hostname is the symbolic name of the remote server. The mapping can set the following flags: $N - Immediately reject the message with an "invalid host/domain error" Any supplied text will be logged as the reason for rejection but will not be included in the DSN. $I - Skip the current IP without attempting to connect. $A - Replace the current IP address with the mapping result. (185) The ACCESS_ORCPT MTA option has been changed from a simple boolean (0 or 1) to a bit-encoded value. Bit 0 (value 1) has the same effect it always had: It enables the addition of the ORCPT to all the various access mappings. Bits 1-4 (values 2-16), if set, selectivey enable the addition to the ORIG_SEND_ACCESS, SEND_ACCESS, ORIG_MAIL_ACCESS, and MAIL_ACCESS mappings respectively. (186) The new ACCESS_COUNTS MTA option provides a way to get at various types of recipient count information in the various recipient *_ACCESS mappings. ACCESS_COUNTS is bit-encoded in the same way as ACCESS_ORCPT now is (see the previous item for specifics) and if set enables the addition of a set of counts to the end of the access mapping probe string. Currently the format of the count addition is: RCPT-TO-count/total-recipient-count/ Note the trailing slash. It is expected that additional counter information will be added to this field in the future; all mappings making use of this information should be coded to ignore anything following the (current) last slash or they may break without warning. (187) Support for SMTP chunking (RFC 3030) has been added to both the SMTP client and server. This support is enabled by default. Four new channel keywords can be used to control whether or not chunking is allowed. They are chunkingclient - Enable client chunking support (default) chunkingserver - Enable server chunking support (default) nochunkingclient - Disable client chunking support nochunkingserver - DIsable server chunking support The log file action field has been extended to indicate whether or not chunking was used to transfer a given message. Specifically, a C will be appended if chunking is used. Note that ESMTP has to be used for chunking to work, so you'll typically see field values like "EEC" or "DEC". (188) Support has been added for a new caption channel keyword. This keyword is similar to the existing description channel keyword in that it takes a quoted string as an argument that is intended for use in channel displays. The difference is presumably that a "caption" is short than a "description". JES MF appears to need both. (189) A new utility routine has been written to verify domain-level Schema 1 and 2 information in the directory. This utilty routine is accessible to user through a new verify command in the imsimta test -domain program: % imsimta test -domain DOMAIN_MAP> verify Various checks are done by this utility, but the most important by far is verification of canonical domain settings for domains with overlapping user entries. The verification utility can return the following fatal errors: %DMAP-F-CANTGETDN, Cannot obtain DN of domain entry, directory error %DMAP-F-INTDEFERROR, Internal defined flag error on domain '%.*s', aborting %DMAP-F-INTHASHERROR, Internal hash error, aborting %DMAP-F-INTTREESTRUCTERROR, Internal tree structure error, aborting These are all indicative of an internal error in the verification code and should never occur. The following domain errors can be reported: %DMAP-E-ALIASTOOLONG, Domain alias '%s' in entry with DN '%s' is too long %DMAP-E-BASEDNTOOLONG, Base DN pointer '%s' in entry for domain '%.*s' is too long %DMAP-E-CANONICAL, Overlapping domains '%.*s' and '%.*s' defined by entries '%.*s' and '%.*s' have different canonical domains '%.*s' and '%.*s' %DMAP-E-CANONICALINVALID, Canonical domain '%.*s' defined/referenced by domain entry with DN '%.*s' is syntactically invalid %DMAP-E-CANONICALTOOLONG, Canonical name '%s' in entry for domain '%.*s' is too long %DMAP-E-CANTCONVDCDN, Cannot convert DN '%s' in DC tree to domain name %DMAP-E-CANTEXTALIAS, Empty alias pointer attribute in '%.*s' domain alias entry %DMAP-E-DOMAININVALID, Domain name '%.*s' defined/referenced by domain entry with DN '%.*s' is syntactically invalid %DMAP-E-DOMAINMULTDEF, Domain '%s' multiply defined by entries with DNs '%s' and '%s' %DMAP-E-DOMAINTOOLONG, Domain '%s' in entry with DN '%s' is too long %DMAP-E-DOMAINUNDEF, Domain name '%.*s' referenced by domain entry with DN '%.*s' never defined %DMAP-E-EMPTYCANONICAL, Domain '%.*s' has an empty canonical name %DMAP-E-INVALIDBASEDN, Base DN pointer '%.*s' in entry for domain '%.*s' is not a valid DN %DMAP-E-MULTICANONICAL, Multivalued canonical name in entry for domain '%.*s', used value '%s' ignored '%s' %DMAP-E-NOBASEDN, Domain '%.*s' has no base DN %DMAP-E-EMPTYBASEDN, Domain '%.*s' has an empty base DN %DMAP-E-NODOMAINNAME, Domain entry with DN '%s' does not have a domain name The following warnings can be reported: %DMAP-W-DISALLLOWEDATTR, Domain '%.*s' has a disallowed attribute '%s' with value '%s' %DMAP-W-DNTOOLONG, Domain entry DN '%s' is too long %DMAP-W-EMPAPPSTAT, Domain '%.*s' has an empty application status %DMAP-W-EMPDISALLLOWED, Domain '%.*s' has an empty disallowed attribute '%s' %DMAP-W-EMPDOMSTAT, Domain '%.*s' has an empty domain status %DMAP-W-EMPUIDSEP, Domain '%.*s' has an empty UID separator %DMAP-W-INVALIDAPPSTAT, Application status '%s' for domain '%.*s' is invalid %DMAP-W-INVALIDDOMSTAT, Domain status '%s' for domain '%.*s' is invalid %DMAP-W-INVALIDUIDSEP, UID separator '%s' for domain '%.*s' is invalid %DMAP-W-MULTDOMAINNAMES, Domain entry with DN '%s' has multiple domain names, used value '%s' ignored '%s' %DMAP-W-MULTIAPPSTAT, Multivalued application status in entry for domain '%.*s', used value '%s' ignored '%s' %DMAP-W-MULTIBASEDN, Multivalued base DN pointer in entry for domain '%.*s', used value '%s' ignored '%s' %DMAP-W-MULTIDOMSTAT, Multivalued domain status in entry for domain '%.*s', used value '%s' ignored '%s' %DMAP-W-MULTIUIDSEP, Multivalued UID separator in entry for domain '%.*s', used value '%s' ignored '%s' %DMAP-W-MULTIVALIAS, Multivalued alias pointer in entry for domain alias '%.*s', used value '%s' ignored '%s' %DMAP-W-NOBASEDNNODE, Base DN pointer '%.*s' in entry for domain '%.*s' doesn't point at anything %DMAP-W-NODOMAINNAME, Domain entry with DN '%s' has a blank domain alias %DMAP-W-NOENTRIES, No domain entries found, aborting Additional messages will undoubtedly be added to this list over time. (190) The ability to generate :addresses arguments to sieve vacation via an LDAP autoeply attribute has been added to Messaging Server. The new MTA option LDAP_AUTOREPLY_ADDRESSES provides the name of the attribute to use. This option has no value by default. The attribute can be multivalued, with each value specifying a separate address to pass to the :addresses vacation parameter. (191) The new LDAP_DOMAIN_ATTR_CATCHALL_MAPPING can now be used to specify the name of a LDAP domain attribute. This option is not set by default. If set the option specifies the name of a mapping which is consulted when an address associated with the domain fails to match any user entries. The format of the mapping probe is the same as that of the forward mapping, and the USE_FORWARD_DATABASE MTA option controls the format of the probe of this mapping in the same way as the forward mapping. If the mapping sets the $Y metacharacter the resulting string will replace the address being processed. (192) The MTA now fetches the block limit associated with the envelope return address and will set RET=HDRS if no return policy is specified and the message size exceeds the block limit. This prevents nondelivery reports for large messages from being undeliverable themselves. No new options or settings are associated with this change. (193) The $E metacharacter in a mapping template means "exit after processing the current template". There are cases where it is desireable to exit immediately without interpreting the rest of the template. The $+1E metacharacter sequence now produces this behavior. (194) Use of POP-before-SMTP via the MMP is now indicated in mail.log E records by the addition of a "P" to the action code. (195) Use of POP-before-SMTP can now be checked in the various *_ACCESS mappings (except PORT_ACCESS, which occurs before the necessary information has been communicated to the server), the FORWARD mapping, and any domain catchall mapping. The $P metacharacter flag is set if POP-before-SMTP is used. (196) The restriction that the same attribute cannot be assigned to multiple "slots" and hence can have multiple semantics during alias expansion and address reversal. (197) The internal separator character used to delimit multiple subject line tag additions has been changed from space to vertical bar. This makes it possible to add a tag containing spaces, as some spam filters want to do. This change effectively prevents vertical bars from being used in tags, but such usage is almost certainly nonexistant. (198) The MIME specification prohibits the use of a content-transfer-encoding other than 7bit, 8bit, and binary on multipart or message/rfc822 parts. It has long been the case that some agents violate the specification and encode multiparts and message/rfc822 objects. Accordingly, the Messaging Server MTA has code to accept such encodings and remove them. However, recently a different standards violation has shown up, one where a CTE field is present with a value of quoted-printable or base63 but the part isn't actually encoded! If the MTA tries to decode such a message the result is typically a blank messages, which is pretty much what you'd expect. Messages with this problem have become sufficiently prevalent that two new pairs of channel keywords have been added to deal with the problem - interpretation of content-transfer-encoding fields on multiparts and message/rfc822 parts can be enabled or disabled. The first pair is interpretmultipartencoding and ignoremultipartencoding and the second is interpretmessageencoding and ignoremessageencoding. The defaults are interpretmultipartencoding and interpretmessageencoding. (199) Several additional error messages the SMTP server either returns or places in DSNs have been made configurable. The new options and their default values are: ERROR_TEXT_MAILFROMDNSVERIFY invalid/host-not-in-DNS return address not allowed ERROR_TEXT_INVALID_RETURN_ADDRESS invalid/unroutable return address not allowed" ERROR_TEXT_UNKNOWN_RETURN_ADDRESS invalid/no-such-user return address ERROR_TEXT_ACCEPTED_RETURN_ADDRESS return address invalid/unroutable but accepted anyway ERROR_TEXT_SOURCE_SIEVE_ACCESS source channel sieve filter access error ERROR_TEXT_SOURCE_SIEVE_SYNTAX source channel sieve filter syntax error: ERROR_TEXT_SOURCE_SIEVE_AUTHORIZATION source channel sieve filter authorization error ERROR_TEXT_TRANSACTION_LIMIT_EXCEEDED number of transactions exceeds allowed maximum" ERROR_TEXT_INSUFFICIENT_QUEUE_SPACE insufficient free queue space available ERROR_TEXT_TEMPORARY_WRITE_ERROR error writing message temporary file ERROR_TEXT_SMTP_LINES_TOO_LONG lines longer than SMTP allows encountered; message rejected ERROR_TEXT_UNNEGOTIATED_EIGHTBIT message contains unnegotiated 8bit (200) We're seeing cases of overly agressive SMTP servers which will issue a "5xy bad recipient" response to the first RCPT TO and then disconnect immediately. (This is of course a flagrant standards violation.) The problem is Messaging Server treats this as a temporary error (which of course it is) and tries later, only to get the same result. A better thing to do which works around this server bug is to handle the one recipient as bad and requeue any remaining recipients for a later retry. (201) Two new actions are availabile to system sieves: addconversiontag and setconversiontag. Both accept a single argument: A string or list of conversion tags. Addconversiontag adds the conversion tag(s) to the current list of tags while setconversiontag empties the existing list before adding the new ones. Note that these actions are performed very late in the game so setconversiontag can be used to undo all other conversion tag setting mechanisms. (202) A new MTA option, INCLUDE_CONVERSIONTAG, has been added to selectively enable the inclusion of conversion tag information in various mapping probes. This is a bit-encoded value. The bits are assigned as follows: pos value mapping 0 1 CHARSET_CONVERSIOn - added as ;TAG= field before ;CONVERT 1 2 CONVERSION - added as ;TAG= field before ;CONVERT 2 4 FORWARD - added just before current address (| delim) 3 8 ORIG_SEND_ACCESS - added at end of probe (| delim) 4 16 SEND_ACCESS - added at end of probe (| delim) 5 32 ORIG_MAIL_ACCESS - added at end of probe (| delim) 6 64 MAIL_ACCESS - added at end of probe (| delim) In all cases the current set of tags appears in the probe as a comma separated list. (203) The sieve envelope test now accepts "conversiontag" as an envelope field specifier value. The test checks the current list of tags, one at a time. Note that the :count modifier, if specified, allows checking of the number of active conversion tags. This type of envelope test is restricted to system sieves. Also note that this test only "sees" the set of tags that were present prior to sieve processing - the effects of setconversiontag and addconversiontag actions are not visible. (204) Trailing dots on domains, e.g. "foo@bar.", are illegal in email but have been tolerated in some contexts by Messaging Server for a long time. RFC 1123 points out that trailing dots are syntactically illegal in email but notes that some convention needs to exist in user interfaces where short form names can be used. Accordingly, it may be handy in contexts like SMTP submission to be able to accept addresses with trailing dots, remove the dot while attaching special semantics to its presence. Accordingly, Messaging Server has modified in two ways: (1) Trailing dots are now accepted by the low-level address parser, making it possible to use them in context where they could not previously be used, like addresses inside of group constructs. (2) Trailing dots, when specified will cause a rewrite of the address with a trailing dot. If the rewrite with a trailing dot isn't found or otherwise fails rewriting will continue as before without the trailing dot. (205) Metacharacter substitutions can now be specified in mgrpModerator, mgrpAllowedBroadcaster and mgrpDisallowedBroadcaster attributes. In particular, the various address-related metacharacter sequences ($A for the entire address, $U for the mailbox part, $D for the domain part) refer to the current envelope from address and can in some cases be used to limit the results returned by the URL to entries that are likely (or guaranteed) to match. This may make authorization checks much more efficient. The new MTA option PROCESS_SUBSTITUTIONS controls whether or not substitutions are performed in various LDAP attributes that specify a URL. This is a bit-encoded value, with the bits defined as follows: Bit Value 0 1 Enables substitutions in mgrpDisallowedBroadcaster if set 1 2 Enables substitutions in mgrpAllowedBroadcaster if set 2 4 Enables substitutions in mgrpModerator if set 3 8 Enables substitutions in mgrpDeliverTo if set 4 16 Enables substitutions in memberURL The PROCESS_SUBSTITUTIONS MTA option defaults to 0, meaning that all of these substitutions are disabled by default. Note that the information available for substitution varies depending on whether the attribute is used for authorization checks or for actual list expansion. For authorization attributes the whole address ($A), domain ($D), host ($H), and local-part ($L) are all derived from the authenticated sender address. In the case of list expansion attributes all of these substitution values are derived from the envelope recipient address that specified the list. In both cases, however, the subaddress substitution ($S) is derived from the current envelope recipient address. The ability to access subaddress information in list expansion URLs makes it possible to define "metagroups", that is, a single group entry that in effect creates an entire collection of different groups. For example, a group with a mgrpDeliverTo value of: ldap:///o=usergroup?mail?sub?(department=$S) would make it possible to send mail to every member of a given department with an address of the form group+department@domain.com. Note that a mechanism like a forward mapping could be used to alter the syntax if subaddresses are seen as too difficult. 206) New MTA option LDAP_DOMAIN_ATTR_UPLEVEL. This option specifies the name of a domain-level attribute used to store a domain-specific uplevel value which overrides the value of the DOMAIN_UPLEVEL MTA option for this one domain. Note that this attribute is only consulted if the domain is looked up. This means that setting bit 0 of this value to 1 for a domain won't make subdomains of the domain match unless bit 0 of DOMAIN_UPLEVEL is also set. As such, the way to get subdomain matching for some domains but not others is to set bit 0 of DOMAIN_UPLEVEL (this enabling subdomain matches for all domains) then clear bit 0 of the attribute for the domains where you don't want uplevel matching to occur. (207) Rewrite rules can now be used to override the default ALIAS_MAGIC setting. Specifically, a construct of the form $nT, where n is an appropriate value for the ALIAS_MAGIC MTA option, overrides the setting for the domain when the rule matches during alias expansion. ((208) $U in a PORT_ACCESS mapping template can now be used to selectively enable channel level debugging. (209) In 6.2 and earlier the PORT_ACCESS mapping was only reevaluated by the SMTP server (as opposed to the dispatcher) when bit 4 (value 16) of the LOG_CONNECTION MTA option is set, SMTP auth is enabled, or both. Additionally, evaluation only occurred when an AUTH, EHLO, or HELO command was issued. This has now been changed; PORT_ACCESS is now evaluated unconditionally as soon as the SMTP server thread starts, before the banner is sent. PORT_ACCESS may be reevaluated with different transport information when proxying from the MMP is used. (210) A useful spam-fighting strategy is to delay sending the SMTP banner for a brief time (half a second, say), then clear the input buffer, and finally send the banner. The reason this works is that many spam clients are not standards-compliant and start blasting SMTP commands as soon as the connection is open. Spam clients that do this when this capability is enabled will lose the first few commands in the SMTP dialogue, rendering the remainder of the dialogue invalid. This feature has now been implemented in Messaging Server. It can be enabled unconditionally by setting the BANNER_PURGE_DELAY SMTP channel option to the number of centiseconds to delay before purging and sending the banner. A value of 0 disabled both the delay and purge. The PORT_ACCESS mapping can also be used to control this capability. Specifying $D in the template causes an additional argument to be read from the template result, after the mandatory SMTP auth rulset and realm and optional application info addition. This value must be an integer with the same semantics as the BANNER_PURGE_DELAY value. Note that any PORT_ACCESS mapping setting overrides the BANNER_PURGE_DELAY SMTP channel option. (211) Added channel keywords acceptalladdresses and acceptvalidaddresses. Keyword acceptvalidaddresses is the default and corresponds to the MTA's standard behavior where any recipient errors are reported immediately during the SMTP dialogue. If the keyword acceptalladdresses is specified on a channel, then all recipient addresses are accepted during the SMTP dialogue. Any invalid addresses will have a DSN sent later. (212) Support has been added for postprocessing LDAP expansion results with a mapping. The new LDAP_URL_RESULT_MAPPING MTA option can be used to specify the name of a group attribute which in turn specifies the name of a mapping. This mapping will be applied to any results returned by expanding either a mgrpDeliverTo or memberURL attribute. The mapping probe will be of the form: LDAP-URL|LDAP-result If the mapping returns with $Y set the mapping result string will replace the LDAP result for alias processing purposes. If the mapping returns with $N set the result will be skipped. This mechanism can be used to define groups based on attributes that don't contain proper email address. For example, suppose a company has placed pager numbers in all their user entries. Messages can be sent to these numbers via email by suffixing them with a particular domain. A group could then be defined as follows: (a) Define a new mgrpURLResultMapping attribute in the directory and set the LDAP_URL_RESULT_MAPPING MTA option to this attribute's name. (b) Define a page-all group with the following attributes: mgrpDeliverto: ldap:///o=usergroup?pagerTelephoneNumber?sub mgrpURLResultMapping: PAGER-NUMBER-TO-ADDRESS (c) Define the mapping: PAGER-NUMBER-TO-ADDRESS *|* "$1"@pagerdomain.com$Y Even more interesting effects can be acheived by combining this mechanism with the PROCESS_SUBSTITUTION mechanism described in item 205 above. For example, it would be easy to create a metagroup where sending to an address of the form pager+user@domain.com sends a page to the user named "user". (213) Setting the LOG_QUEUE_TIME MTA option to 1 now causes an additional field to be selectively written to connection log records. This new field appears immediately after any diagnostic information and is labelled as "ct" in the XML-based log format. The value of this field is an integer count of the number of seconds that elapsed when performing the operation. So, for connection open ("O") records, the time shown is the number of seconds needed to open the connection. For connection close ("C") records it indicates the number of seconds the connection was open. For connection failure records ("Y") the value indicates the amount of time that was spent attempting to open the connection. (214) "S" transaction log entries now increment the various submitted message counters associated with the channel. (215) The $( metacharacter in a FROM_ACCESS specifies that an address should be read from the result string and used to replace the current overriding postmaster address. $) has the same effect with the added constraint that the overriding postmaster address must not be set prior to invoking the mapping. This allows for specific postmaster addresses to be used with addresses in nonlocal domains - domain postmaster addresses by definition only work with locally defined domains. The override address is (currently) the last string read from the FROM_ACCESS result prior to reading any $N/$F failure result. (216) The capture sieve action now has two optional nonpositional parameter: :dsn and :message. Only one of these can be specified in a single capture action. :dsn is the default, and encapsulates the captured message inside a special type of DSN. :message eliminates the enacapsulation and behaves more like a redirect. But unlike redirect, capture :message is only available to system sieves, always takes effect even when a more specific sieve specifies some other sort of action, and the envelope from address will be overridden with the address of the sieve owner. (217) The MTA now checks to make sure the UID attribute has a single value and reports an alias expansion error if it does not. The UID attribute is required to be single-valued in order to insure the user has a single, unique mailbox. (218) Two additional MTA options have been added to support more efficient domain lookups from user base DNs. They are: LDAP_BASEDN_FILTER_SCHEMA1 String specifying filter used to identify Schema 1 domains when performing baseDN searches. Default is the value of LDAP_DOMAIN_FILTER_SCHEMA1 if that MTA option is specified. If neither option is specified the default is "(objectclass=inetDomain)". LDAP_BASEDN_FILTER_SCHEMA2 String specifying additional filter elements used to identify Schema 2 domains when performing baseDN searches. Default is the value of LDAP_DOMAIN_FILTER_SCHEMA2 if that MTA option is specified. If neither option is specified the default is an empty string. (219) A new MTA option MESSAGE_SAVE_COPY_FLAGS has been added to control how the probes are constructed for the MESSAGE-SAVE-COPY mapping. If bit 0 (value 1) is set it adds the transport and application information to the beginning of the probe, if bit 1 (value 2) is set the original source channel is added, if bit 2 (value 4) is set the most recent conversion tag string is added. If all three bits are set the overall probe format is: transport|orig-source-channel|conversion-tags|queue-channel|return-address|D|filename (220) The LDAP_OPTIN1 through LDAP_OPTIN8 MTA options specify attributes for per-user optins to spam filtering based on destination addresses. There are now 8 new MTA options, LDAP_SOURCE_OPTIN1 through LDAP_SOURCE_OPTIN8, that provide comparable originator-address-based per-user spam filter optins. (221) Some additional switches have been added to imsimta test -rewrite: -saslused - Set internal flag indicating SASL authentication was used -tlsused - Set internal flag indication TLS is in use -esmtpused - Set internal flag indicating ESMTP is in use -lmtpused - Set internal flag indicating LMTP is in use -proxyused - Set internal flag indicating proxy authentication was used Only -saslused and -tlsused are available in 6.2; the other depend on other changes made in 6.3 and hence cannot be implemented in earlier versions. -lmtpused and -esmtpused cannot be set at the same time. -proxyused requires that -esmtpused or -lmtpused also be set. (222) New LMTP channel option MAILBOX_BUSY_FAST_RETRY. If set to 1 (the default) a 4.2.1 Mailbox busy error in response to LMTP message data is handled by retrying the message after a random but short interval; normal message backoff values do not apply. Setting the option to 0 disables this behavior. |

此发行版中对 Red Hat Linux 3 平台的支持已过时,并将在以后的发行版中删除。Red Hat Linux 4 上将继续支持 Communications Suite 5。
在此发行版中,有两种用于发送事件通知和警报的通知服务:Sun Java System Message Queue (JMQ) 和事件通知服务 (Event Notification Service, ENS)。在将来的发行版中,Communications Suite 产品只使用 JMQ,而不再使用 ENS。但在此发行版中,Messaging Server、Calendar Server 和 Instant Messaging 对 ENS 仍具有内部依赖性;因此,您可以继续使用 ENS。
对于此发行版,Messaging Server IMAP IDLE 功能需要使用 ENS。Messaging Server 对 ENS 没有其他依赖性。如果不使用 IMAP IDLE,则可以只使用 JMQ 来发送事件通知。
如果要使用 IMAP IDLE,则必须配置 ENS 通知插件。您还可以通过配置 JMQ 通知插件将 JMQ 用于邮件通知。(Messaging Server 允许您配置多个通知插件。)
表 3–2 中列出的 configutil 参数已过时,并已从 Messaging Server 产品中删除。
如果将 Messaging Server 从早期发行版升级到 Messaging Server 6.3 ,则表 3–2 中列出的参数将在升级后从配置中删除。在升级之前,Sun 建议您将 configutil 输出保存为文件。

Messaging Server 6.3 要求使用共享安全组件 NSS 3.9.3 版。
有关产品版本相关性的详细信息,请参见《Sun Java Enterprise System 5 Installation Guide for UNIX》和《Sun Java Enterprise System 5 Release Notes for UNIX》。
部署 Messaging Server 产品时,要求在本地网络中具有高质量的缓存 DNS 服务器。Messaging Server 在很大程度上要依靠 DNS 服务器的响应率和可伸缩性。
另外,确保在设置中正确配置了 DNS,并清楚地指定了路由至非本地子网中的主机的方法:
/etc/defaultrouter 应包含网关系统的 IP 地址。该地址必须位于本地子网中。
/etc/resolv.conf 存在并包含可到达 DNS 服务器和域后缀的相应条目。
在 /etc/nsswitch.conf 的 hosts: 行中添加 files、dns 和 nis 关键字。关键字 files 必须在 dns 和 nis 之前。
确保 FQDN 是 /etc/hosts 文件中的第一个主机名。
如果 /etc/hosts 文件中的 Internet 主机表与以下内容类似:
123.45.67.89 budgie.west.sesta.com 123.45.67.89 budgie loghost mailhost |
请更改该表以使主机的 IP 地址位于一行。请确保第一个主机名为全限定域名。例如:
123.45.67.89 budgie.west.sesta.com budgie loghost mailhost |
在 Solaris 9 或 Solaris 10 环境中,Messaging Server 可以运行在以下 Sun Cluster 和 Veritas Cluster Server 版本上:
产品 |
支持的版本 |
---|---|
Sun Cluster (SC) |
SPARC:3.0、3.1 x86:3.1 Update 4 Linux:不支持 |
Veritas Cluster Server (VCS) |
SPARC:3.5、4.0、4.1、5.0 x86:3.5、4.0、4.1、5.0 Linux:不支持 |
建议将以下文件系统用于邮件存储库:
LUFS(日志记录 UFS)。
VxFS(Veritas 文件系统)。如果正确配置了 Veritas 文件系统,它将会提供良好的系统性能。如果使用 VxVM (Veritas Volume Manager),则需要仔细观察是否已将卷和卷的日志文件设置为定期清理。
HAStoragePlus 文件系统(适用于 Sun Cluster 安装)。HAStoragePlus 文件系统可以比默认的 Sun Cluster 全局文件系统提供更好的性能。
NFS(Network File System,网络文件系统)。
可以在 MTA 中继计算机上针对 LMTP、自动回复历史记录和消息碎片整理使用 NFS。请参见《Sun Java System Messaging Server 6.3 管理指南》。此外,BSD 类型的邮箱 (/var/mail/ ) 和邮件存储库都支持 NFS。以下版本的 NFS 经过认证可用于 Messaging Server:Sun StorEdge 5310 NAS 设备。
以下安装说明适用于 Messaging Server 6.3 发行版:
可以使用 Communications Services 安装程序来安装 Messaging Server。
有关安装说明,请参见《Sun Java Communications Suite 5 Installation Guide》。
接着,必须通过执行以下步骤来配置 Messaging Server:
运行目录服务器准备工具 comm_dssetup.pl。
运行 Messaging Server 配置程序。
有关配置说明,请参见《Sun Java System Messaging Server 6.3 管理指南》
在最新版本的 comm_dssetup.pl(此程序用于准备目录服务器以供 Messaging Server 使用)中实现了以下更改:
无提示安装:密码更改
-w dirmanager_passwd 已过时,建议使用 -j passwd_file
以了解对 comm_dssetup.pl 的其他更改信息。
如果要从早期发行版升级到 Messaging Server 6.3 ,请按照《Sun Java Communications Suite 5 Upgrade Guide》中的升级说明执行操作。
首次安装 Messaging Server 或从早期版本的 Messaging Server 进行升级时,请确保 Solaris 系统上的 /etc/hosts 文件中包含以下条目:
<ip-of system> <FQHN> <hostname>
例如,129.158.230.64 budgie.siroe.varrius.com budgie
在 Solaris 10 平台上,必须将全限定域名 (Fully Qualified Domain Name, FQDN) 同时添加到 /etc/hosts 文件和 /etc/inet/ipnodes 文件中。否则,您将收到一条错误消息,指出您的主机名不是全限定域名。
升级 Messaging Server 后,必须按以下步骤设置 ulimit,以增加文件描述符的数量:
ulimit -n number_of_file_descriptors
例如:
ulimit -n 100000
有关升级过程的详细信息,请参见《Sun Java Communications Suite 5 Upgrade Guide》。
如果您选择将 Messaging Server 6.3 后端用于 Messaging Server 6 2005Q4 前端,则需要按以下步骤配置前端,以便在没有 Administration Server 的情况下运行:
使用 Communications Suite 5 安装程序安装和配置 Messaging Server 6.3 后端。
运行 Java Enterprise System 2005Q4 安装程序来安装 Messaging Server 6 2005Q4 前端,并在出现提示时选择 Configure Later 选项。
在文本编辑器中打开 msg-svr-base/lib/config-templates/DevsetupDefaults.properties 。
更改以下命令行:
ADMINSERVER_SERVERROOT_CONF = /etc/mps/admin/v.5.2/shared/config/serverroot.conf
更改为:
ADMINSERVER_SERVERROOT_CONF = NO_ADMIN_SERVER
要在运行 Messaging Server 6.3 时使用 iPlanet Delegated Administrator 清除用户,请参见使用 iPlanet Delegated Administrator 和 Messaging Server 6.3 清除用户。
下表介绍了 Messaging Server 的兼容性问题:
不兼容性 |
解决方法 |
注释 |
---|---|---|
用于为 Messaging Server(Calendar Server 和 Delegated Administrator)准备目录服务器的程序 comm_dssetup.pl 已被修改,可同时用于 Directory Server 6.0 和 Directory Server 5.x:交互模式:服务器根目录和目录服务器实例 |
目录服务器实例驻留在服务器根目录或明确的目录服务器实例目录中。早期版本的目录服务器使用服务器根目录(其中包含多个实例和配置信息)概念。Directory Server 6 不再使用服务器根目录。实例可能位于任何位置。对于此问题,用户需要:1) 指定实例目录。或者,如果用户使用早期版本的目录服务器,则可以:2) 指定包含实例的服务器根目录。系统将向您提示其他问题,以便从服务器根目录中选择实例。或者, 3) 以前使用 Directory Server 5x 而现在使用 Directory Server 6 的用户可以将所有目录服务器实例手动放在父目录(以前称为服务器根目录)之下。 注 – 服务器根目录这一术语已从 Directory Server 6 中删除。 |
无附加注释 |
用于为 Messaging Server(Calendar Server 和 Delegated Administrator)准备目录服务器的程序 comm_dssetup.pl 已被修改,可同时用于 Directory Server 6.0 和 Directory Server 5.x:无提示安装:服务器根目录 |
在早期版本的无提示安装中,您可能需要同时指定服务器根目录和实例目录。如果您使用 Directory Server 5.x,则仍需执行此操作。由于 Directory Server 6.0 中没有服务器根目录,您需要指定目录服务器实例的父目录。 |
无附加注释 |
目录准备工具 (comm_dssetup.pl) 的位置已更改。 |
comm_dssetup.pl 现在位于其自身的软件包中,该软件包安装在 /opt/SUNcomds (Solaris) 或 /opt/sun/comms/dssetup (Linux) 中。 需要更新用于指定旧路径的现有脚本。 |
要安装该软件包,请确保已在相应的安装程序面板中选择了相应的目录准备工具。 |
在 Messaging Server 5.x 中,管理员可以使用 IMAP list 命令显示邮件存储库中的所有文件夹。对于典型的邮件存储库,使用该命令将导致服务器显示一个非常长的列表。 在 Messaging Server 6.x 中,当管理员运行 IMAP list 命令时,仅显示显式共享的文件夹。 |
要列出邮件存储库中的所有文件夹,请使用 mboxutil 实用程序。 |
有关 mboxutil 实用程序的详细信息,请参见《Sun Java System Messaging Server 6.3 管理指南》。 |
已更改 Delegated Administrator 的配置程序。 |
安装 Delegated Administrator 并运行配置程序。当前程序位于: /opt/SUNWcomm/sbin/ config-commda (Solaris) /opt/sun/comms/config-commda (Linux) |
安装此版本的 Messaging Server 时,请升级到新的 Delegated Administrator。 |
应同时升级 Messaging Server 和已改为使用 IMAP 协议的 Webmail (6397425, 6397451, 2137362) |
升级前端服务器之前必须先升级后端服务器。使用 IMAP 协议的 Webmail 和后端邮件存储库必须是同一产品版本。有关详细信息,请参见 Sun Java Communications Suite 5 Upgrade Guide。 |
无附加注释 |
此 Communications Express 发行版与早期版本的 Messaging Server 不兼容。 |
如果要升级 Communications Express,必须同时升级 Messaging Server。 |
这也适用于 Calendar Server。 有关 Communications Express 的详细信息,请参见第 6 章,Sun Java System Communications Express 6.3 发行说明。 |
有关在 Messenger Express 和 Communications Express 的各种浏览器上是否可以使用 RTF/HTML 编辑功能需要进行的澄清。 (6311363) |
|
无附加注释。 |
单击 Portal Server 中的 Communications Express 时会显示“session.timeout 请重新登录”弹出式错误消息。(6417988) |
忽略该弹出式错误消息,关闭窗口,然后继续使用 Communications Express。 |
无附加注释。 |
如果将 Messaging Server 用于 Access Manager 单一登录,则它不支持 Java Enterprise System 2004Q2 Access Manager Server。但支持 Access Manager 6.3 和更高版本。 |
不支持 Java Enterprise System 2004Q2 Access Manager Server 的 Messaging Server 特定版本包括:
|
在升级 Messaging Server 之前先升级 Access Manager (JES 2004Q2)。 |
Access Manager 现在具有两种安装类型:Realm(版本 7.x 样式)和 Legacy(版本 6.x 样式)。 |
如果与 Messaging Server、Calendar Server、Instant Messaging、Delegated Administrator 或 Portal Server 一起安装 Access Manager,则必须选择 Legacy 模式(版本 6.x 样式)。请参见 《Sun Java System Access Manager 7 2005Q4 Release Notes》 |
如果没有正确安装 Access Manager,则将无法运行 Delegated Administrator。 |
如果您要使用 iPlanet Delegated Administrator 并升级到 Messaging Server 6.3,则无法像在 Messaging Server 早期版本中那样使用 imadmin user purge 命令从目录中删除用户(6486836)。请通过执行以下步骤来清除用户。
发生此兼容性问题的原因是 Messaging Server 6.3 中已删除了 Administration Console 和 Administration Server。使用早期版本的 Messaging Server,您可以继续像以前一样使用 imadmin user purge。
iPlanet Delegated Administrator(最初用于 Messaging Server 5.x)是已过时的实用程序。它与 Communications Suite Delegated Administrator(随 Messaging Server 6.x 引入)是不同的工具。Communications Suite Delegated Administrator 支持 Schema 2,而 iPlanet Delegated Administrator 支持 Schema 1。(某些已将 Messaging Server 升级到 6.x 但仍位于 Schema 1 中的管理员还继续使用 iPlanet Delegated Administrator 来置备用户。)
应用 iPlanet Delegated Administrator 修补程序 1.2p3。
可在以下站点下载此修补程序:
http://www.sun.com/download/index.jsp?cat=Collaboration%20%26%20Communication&tab=3
转至 Delegated Administrator 1.2 Patch 3 for Messaging。此修补程序允许 imadmin user purge 命令使用与 Messaging Server 6.3 兼容的方式运行。执行此过程中的其余步骤可启用该新功能。
修改 iPlanet Delegated Administrator resource.properties 文件中的 MsgSvrN-adminurl 属性。
MsgSvrN-adminurl 属性用于设置 Administration Server 的 url。如果将此属性设置为实际的 url,则 imadmin user purge 命令将尝试查找 Administration Server,但不会得到响应。imadmin user purge 命令将返回一个错误。
必须将 MsgSvrN-adminurl 设置为以下值:NO_ADMIN_SERVER。
默认情况下,resource.properties 文件位于以下路径中:
iDA_Install_Directory /nda/classes/netscape/nda/servlet/resource.properties
多个邮件存储库已升级到 Messaging Server 6.3:
MsgSvrN-adminurl 中的值 N 是必须使用特定值(如 0)替换的变量,该变量可标识已升级到 Messaging Server 6.3 的邮件存储库系统。如果您已在 Messaging Server 6.3 中部署了多个后端邮件存储库,则必须对 MsgSvrN-adminurl 属性的每个实例更改此值。
例如,如果您有三个后端邮件存储库,则对于所有这三个存储库,您都必须在 resource.properties 文件中更改此属性。例如,您可能需要更改 MsgSvr0-adminurl、MsgSvr1-adminurl 和 MsgSvr2-adminurl 属性。
多个邮件存储库使用不同版本的 Messaging Server:
假定您已部署多个邮件存储库,并且只将某些存储库升级到 Messaging Server 6.3,而另一些存储库仍留在早期版本的 Messaging Server 中。在这种情况下,只需对已升级到 Messaging Server 6.3 的存储库更改 MsgSvrN-adminurl 属性。
当您对已将 MsgSvrN-adminurl 属性更改为 NO_ADMIN_SERVER 的存储库运行 imadmin user purge 命令时,该命令将以下面步骤 5 中所述的新方式运行。
当您对 MsgSvrN-adminurl 属性保持不变(仍指向 Administration Server url)的存储库运行 imadmin user purge 命令时,该命令将按照以前的方式运行。
重新启动已部署了 iPlanet Delegated Administrator 的 Web Server。
必须重新启动正在运行 iPlanet Delegated Administrator 的 Web Server,才能使 resource.properties 文件中的更改生效。
使用 imadmin user delete 命令将用户标记为已删除。
imadmin user delete 可将 inetUserStatus 属性设置为“已删除”。要删除多个用户,请使用 -i 选项。例如:
imadmin user delete -D chris -L user1 -n siroe.com -w bolton
使用 msuserpurge 命令删除用户的邮箱。
msuserpurge 将查找 inetUserStatus 或 mailUserStatus 设置为已删除的所有用户条目,然后从邮件存储库中清除这些用户邮箱,并将 mailUserStatus 设置为已删除。例如:
msuserpurge -d domain
必须在执行下一个步骤(从目录中删除用户条目)之前运行 msuserpurge,否则用户邮箱将处于孤立状态。
可以使用 configutil 参数 local.schedule.userpurge 来安排 msuserpurge 命令的运行时间。例如:
configutil -o local.schedule.userpurge -v "30 2 * * 0 /opt/SUNWmsgsr/lib/msuserpurge -g 20" |
在前面的示例中,msuserpurge 将在星期日的凌晨 2:30 运行。它将删除标记为删除并且时间超过 20 天的所有用户的邮箱。
使用 imadmin user purge 命令从目录中删除用户条目。
在早期版本中,此命令执行以下操作:
搜索目录以查找标记为已删除的用户。
从目录中删除每个用户的个人通讯录。
从邮件存储库中删除每个用户的邮箱。
如果用户的 inetUserStatus 属性设置为已删除,该用户条目将被删除。如果用户的 mailUserStatus 设置为已删除,将从条目中删除邮件属性。
现在,由于您修改了MsgSvr0-adminurl 属性,因此不会调用 Administration Server。将显示一条消息,通知您 Administration Server 未被调用。未执行上述步骤 c。在步骤 3 中邮箱已被 msuserpurge 删除。
在 Messaging Server 6.3 中,如果用户的 mailuserstatus 设置为已删除(由 msuserpurge 设置),并且用户条目中不存在其他服务,则 imadmin user purge 命令将从目录中删除该用户条目。
如果用户条目中还存在其他服务(如日历服务)的属性,则不会删除该条目。

安装 SUNWma 时创建了 /opt/etc 目录
解决方法:安装产品后手动删除该目录。将来的发行版中将修复此问题。
本部分介绍 Messaging Server 产品中的已知问题。
在 Directory Server 5.x 版中,ACI 对 LDAP 搜索性能有微弱影响。
此问题对 Messaging Server 执行的许多搜索都有影响。
解决方法:要加快搜索速度,可以通过以下命令使用目录管理器凭证来访问目录:
msg-svr-base/sbin/configutil -o local.ugldapbinddn -v "rootdn"
msg-svr-base/sbin/configutil -o local.ugldapbindcred -v "rootdn_passwd"
其中,rootdn 和 rootdn_passwd 是目录服务器管理员的证书。
要让使用 configutil 所做的更改生效,通常需要重新启动受到影响的服务器。
解决方法:无。
如果将 Microsoft Outlook Express 用作 IMAP 邮件客户端,则可能无法正确显示已读和未读标志。
这是 Microsoft Outlook Express 客户端存在的已知问题。
解决方法:设置以下配置变量:
configutil -o local.imap.immediateflagupdate -v yes
如果执行以上方法时遇到性能问题,建议不要继续使用该方法。
如果在 /etc/hosts 文件中使用了短格式的域,则访问控制过滤器将不起作用。
如果 /etc/hosts 文件中包含短格式域名,则在访问控制过滤器中使用主机名时将出现问题。IP 地址查找返回了短格式域名时,匹配将失败。因此,应确保在 /etc/hosts 文件中使用全限定域名。
解决方法:无。
MoveUser 实用程序对于包含的子文件夹数大于 1024 的邮箱不起作用。
据报告称,如果用户的邮箱包含 1024 个以上子文件夹,则 MoveUser 实用程序在尝试删除该用户帐户时将停止。
解决方法:无。
Messenger Express Multiplexor (MEM) 没有相应的配置选项来使用操作系统解析器或 NSCD。
解决方法:将系统配置为高速缓存专用 DNS 服务器,以获得高速缓存 MX 和 A 记录的好处。
GB18030(中国国家标准)字符集现在可由 MTA 识别。
实现此支持导致已编译的字符集数据发生更改。可能需要在升级后运行 imsimta chbuild。
默认情况下启用了 XSTA 和 XADR 命令。
安装后,默认情况下已启用 SMTP 扩展命令 XSTA 和 XADR,远程和本地用户可利用该命令检索敏感信息。
解决方法:在 <msg-svr-base>/config/tcp_local_option 文件(如有必要请创建此文件)中添加以下行,以禁用 XSTA 和 XADR 命令:
DISABLE_ADDRESS=1 DISABLE_CIRCUIT=1 DISABLE_STATUS=1 DISABLE_GENERAL=1
imsimta start 未启动分发程序和作业控制器。
只有在 watcher 进程运行时,imsimta start、imsimta restart 和 imsimta refresh 命令才起作用。
新的 start-msg 和 stop-msg 命令已取代了 imsimta start 和 imsimta stop(这两个命令已过时,并要在将来的发行版中删除)。
有关 start-msg 和 stop-msg 命令的详细信息,请参阅 Messaging Server 管理指南。
解决方法:无。
客户端证书验证需要正确的 certmap.conf 文件内容。
certmap.conf 配置文件指定将证书映射到 LDAP 目录中的条目的方法。默认情况下,证书主题(带有两行注释)包含 LDAP 目录条目的准确 DN。
另有一种常见的替代做法,即从证书的主题中提取特定属性,然后在目录中搜索该属性。
解决方法:要实现此替代做法,需要将以下内容:
certmap default default #default:DNComps #default:FilterComps e, uid
更改为:
certmap default default default:DNComps default:FilterComps e
使用代理服务器时,无法通过 Internet Explorer 6.0 SP1 登录 Messaging Server。
在客户端 PC 上的 Internet Explorer 6.0 SP1 中使用 HTTP 代理时,可能会遇到登录 Messaging Server 困难。该问题可能是由于非标准的兼容代理服务器造成的,无法在 Messaging Server 中修复。
使用非标准组织 DN 时,配置程序失败。
configure 程序不能在组织 DN 和用户/组后缀之间构建中间 RDN。Schema 1 和 Schema 2 中都存在该问题。
解决方法:在运行 configure 程序之前(或至少在创建组织 DN 之上的 DN 之前)创建组织 DN。
未配置 SSL 时,imta 日志文件中出现 NSS 错误。
这些错误是无碍的,是由于系统在 SSL 配置中找不到 SSL 证书引起的。
解决方法:您可以通过以下步骤在 MTA 和邮件存储库中禁用 SSL:
编辑 imta.cnf 文件并从 tcp_local 和 tcp_intranet 通道中删除通道关键字 maytlsserver。
通过将 service.imap.sslusessl 和 service.pop.sslusessl 均设置为 "no" 来更改以下 configutil 配置参数。
使用 imsimta cnbuild 命令重新编译 MTA 配置。
重新启动服务 (stop-msg/start-msg)。这将不再支持 SSL。如果创建证书后需要在 SSL 模式下配置服务器,请确保将以前所做的更改复原。
在 Solaris 10 上启用 SNMP 后,Messaging Server 无法启动。
解决方法:将 snmpwalk 定向至 snmpdx,而非 snmpd,并直接转至端口 16161 而非端口 161。
store.idx 2 GB 限制的操作方式应与配额相同。
对于 store.idx 文件,邮件存储严格限制为 2 GB。当文件夹增大到使 store.idx 文件超过 2 GB 时,mail.log_current 文件中将显示错误消息。
解决方法:如果可能,请设置一个配额。同时也建议设置策略以使用一些成熟的规则来确保文件夹不会变得太大。
REVERSE_URL 行为已发生更改。
建议您不要更改此属性。
如果您要对地址反向和主要地址存储库使用其他属性,则不应使用 REVERSE_URL。应该将 LDAP_PRIMARY_ADDRESS 设置为要使用的属性。与此相关的问题是,要用于别名查找和别名反向的地址之间存在语义重叠。您也许可以在 LDAP_PRIMARY_ADDRESS、LDAP_EQUIVALENCE_ADDRESSES 和 LDAP_ALIAS_ADDRESSES 插槽之间混用属性。最简单的情况可能是,您只想将 meEndRemetente(而非邮件)同时用于别名查找和别名反向。在这种情况下,您只需将 LDAP_PRIMARY_ADDRESS MTA 选项设置为 meEndRemetente 即可。另一方面,如果您要继续使用邮件属性进行别名查找,则必须将其放入其他某个插槽中才能正常工作。是否允许这样做,取决于您是否使用 mailAlternateAddress 和 mailEquivalentAddress 属性。Messaging Server 6.2 和更低版本允许每个插槽中具有多个属性,但每个目录条目最多只能有一个在给定插槽中结束的属性。在合理情况下,此 Messaging Server 版本放松了上述属性限制(如 LDAP_ALIAS_ADDRESSES 或 LDAP_EQUIVALENCE_ADDRESSES,但不包括 LDAP_PRIMARY_ADDRESS)。
调整已启用的 SSL 密码;默认情况下可以禁用弱 SSL 密码。
对于 Messaging Server 6.3 及以后的版本,默认情况下将禁用弱 SSL 密码套件。这是一项不兼容的更改,因此某些只支持导出级别 SSL 的旧邮件客户端可能会中断。
以下配置选项可用于启用所有密码套件,包括弱密码套件(但 NULL 密码除外)。
对于 MMP:default:SSLAdjustCipherSuites weak+all
对于 IMAP/POP/SMTP/MSHTTPD:configutil -o local.ssladjustciphersuites -v weak+all
但是, 建议您只启用互操作性所需的特定密码套件。例如,通用 SSL_RSA_EXPORT_WITH_RC4_40_MD5 密码套件可以通过 +SSL_RSA_EXPORT_WITH_RC4_40_MD5 启用。56 位密码不像 40 位密码那样弱,因此,如果能够只启用这些密码,则以下密码套件将会生效:+TLS_RSA_EXPORT1024_WITH_DES_CBC_SHA 。
imapd ENS 重新订阅者会泄漏文件描述符。
如果配置了 ENS,则必须同时配置 IDLE。如果配置了 ENS 而没有配置 IDLE,imapd 和 popd 将泄漏文件句柄。
解决方法:无
以下是与 Messaging Server 产品相关的其他问题,这些问题没有错误号:
最大邮箱大小
邮箱索引 (store.idx) 文件具有 2 GB 的严格限制。超过此限制将导致邮件无法传送给用户,并且可能会导致邮件存储库性能问题。有关详细信息,请参见《Sun Java System Messaging Server 6.3 管理指南》中的“由于邮箱溢出而无法传送邮件”。请注意,邮箱中邮件大小的总和可能会超过 2 GB 的限制。
在 option.dat 中,以 #、! 或 ; 符号开头的行被视为注释行。
在 option.dat 文件中,Messaging Server 将以井号 (#)、感叹号 (!) 或分号 (;) 开头的行视为注释行,即使前面一行是以表示行将继续的反斜杠 (\) 结尾也是如此。因此,处理包含这些字符的较长选项(特别是传输选项)时必须特别小心。
有一种方法可以解决传输选项中的自然版式导致连续行以 # 或 ! 开头的问题。
解决方法:在传输选项中,Messaging Server 会忽略分隔各传输选项类型的逗号之后的空格。
例如,原版式为:
DELIVERY_OPTIONS=\ #*mailbox=@$X.LMTP:$M$_+$2S%$\$2I@ims_daemon,\ #&members=*,\ *native=@$X.lmtpnative:$M,\ *unix=@$X.lmtpnative:$M,\ /hold=$L%$D@hold,\ *file=@$X.lmtpnative:+$F,\ &@members_offline=*,\ program=$M%$P@pipe-daemon,\ forward=**,\ *^!autoreply=$M+$D@bitbucket
可以按以下所示添加空格来解决该问题:
DELIVERY_OPTIONS=\ #*mailbox=@$X.LMTP:$M$_+$2S%$\$2I@ims_daemon,\ #&members=*,\ #*native=@$X.lmtpnative:$M,\ #*unix=@$X.lmtpnative:$M,\ #/hold=$L%$D@hold,\ #*file=@$X.lmtpnative:+$F,\ #&@members_offline=*,\ #program=$M%$P@pipe-daemon,\ #forward=**,\ #*^!autoreply=$M+$D@bitbucket
已修改 DOMAIN_UPLEVEL。
DOMAIN_UPLEVEL 的默认值从 1 更改为 0。
用户 ID 中不能使用以下字符:$ ~ = # * + % !@ , { } ( ) / < \> ; :" ” [ ] & ?
此约束将由 MTA 强制执行。允许在用户 ID 中使用这些字符可能会使邮件存储库出现问题。如果要更改 MTA 禁止使用的字符列表,请在 msg_svr_base/config/options.dat 文件中通过列出以逗号分隔的字符的 ASCII 值字符串来设置以下选项:
LDAP_UID_INVALID_CHARS=32,33,34,35,36,37,38,40,41, 42,43,44,47,58,59,60,61,62,63,64,91,92,93,96,123,125,126
请注意,强烈建议不要放松该约束。
目前没有本地化或全球化问题。
本部分介绍特定于 Communications Services 和 Messaging Server 的文档中存在的已知问题。
ha_ip_config 脚本不能设置执行 ENS 所需的所有 ENS 配置参数。
如果要在 HA 环境中运行 ENS,则必须在 ha_ip_config 脚本中设置以下参数:
local.ens.port– ENS 将侦听的端口和 IP 地址(IP 地址可选)。格式为: [address:]port。例如,7997 或 192.168.1.1:7997。如果设置了 local.ens.port,还必须配置 local.store.notifyplugin.enshost 和 local.store.notifyplugin.ensport。
local.storenotify.enshost— ENS 服务器的 IP 地址或主机名。此设置必须与 local.ens.port 中的设置一致。
local.storenotify.ensport– ENS 服务器的 TCP 端口。此设置必须与 local.ens.port 中的设置一致。
对错误 5076486(关于通过 iPlanet Delegated Administrator 1.2 Patch 2 使用 imadmin user purge 命令)的更正
您可以通过 iPlanet Delegated Administrator 1.2 Patch 2 和 Messaging Server 6.x 来使用 imadmin user purge 命令。此旧版本的 Delegated Administrator 不应与第 5 章,Sun Java System Delegated Administrator 6.4 发行说明中所述的当前 Delegated Administrator 产品相混淆。要使用旧版本的 Delegated Administrator,需要按照位于 http://docs.sun.com 的 iPlanet Delegated Administrator 安装文档中所述的过程操作,并进行以下修改:
将 iDA_install_directory/nda/classes/netscape/nda/servlet/ resource.properties 文件中的 MsgSvrN-cgipath 行更改为 MsgSvr0–cgipath=msg-config/Tasks/operation 并重新启动 Web Server。
此外,如果要在群集上运行,则必须确保 Administration Server 与 Messaging Server 始终在同一个节点上运行(对于 6.3 以前的发行版)。
解决方法:无。
Messenger Express Customization Guide 在关于自定义托管域的部分显示了错误的目录名称。
要求用户为每个域创建单独目录时,正确目录应该是 msg-svr-base/config/html,而不是 msg-svr-base/html。
Messenger Express Customization Guide 为 SDK 文件和函数指定了错误的文件路径。
SDK 文件和函数位于 msg-svr-base /examples/meauthsdk 中。
Messenger Express 联机帮助介绍了产品中不存在的某些功能
Messenger Express 联机帮助中介绍了以下功能,但这些功能在产品中不存在:
安全传送邮件(也称为 S/MIME)仅适用于 S/MIME 用户。有关 S/MIME 的信息,请参见《Sun Java System Messaging Server 6.3 管理指南》中的第 24 章 “管理 Communications Express Mail 的 S/MIME”。
自动拼写检查器,此功能在早期的发行版中已删除。
邮件过滤器,此功能需要其他配置。请参见 《Sun Java System Messaging Server 6.3 管理指南》中的“配置 Messenger Express 和 Communications Express 邮件过滤器”。
导航路径;当您要查看用户创建的文件夹时,可以查看导航路径。但是,导航路径在默认文件夹(如“收件箱”、“已发送”文件夹、“草稿”、“垃圾箱”等)中不会显示。
由于 Messenger Express 已过时,因此不会更新 Messenger Express 联机帮助。
没有关于新的共享整理数据库功能的文档。
没有关于该新功能(利用该功能,MTA 系统可以共享整理数据库,因此整理可以在 MTA 系统而不是存储系统中完成)的文档。
解决方法:无。
没有启用 imarchive —s 选项,但却有记录。
当前没有启用 imarchive -s 选项。不过,该选项却记录在《Sun Java System Messaging Server 6.3 Administration Reference》中。会在将来的更新版本中启用该选项。
产品文档中使用了不同的服务器根目录表示法。
服务器根目录(其中存储了 Messaging Server 配置文件)为 msg-svr-base。在 Java Enterprise System 文档中,服务器根目录为 MessagingServer-base。两种表示法指的都是 Messaging Server 服务器根目录。
Messaging Server 6.x 提供了以下可再分发的文件:
只有拥有 Messaging Server 的分发许可,才能够以源文件(HTML 和 Javascript)或二进制文件(GIF 文件)的形式再分发以下文件:
msg-svr-base/config/html(及子目录)
msg-svr-base/install/config/html (及子目录)
不允许分发这些文件本身。
您只能按照 Messaging Server 文档中明确提供的形式来复制和使用(但不能修改)以下标题文件,并且目的只能是创建和分发要同 Messaging Server API 交互的程序、编译客户编写的代码(使用所说明的 API 来实现与 Messaging Server 的交互操作和集成)。
msg-svr-base/examples/meauthsdk/expapi.h
msg-svr-base/examples/tpauthsdk/authserv.h
msg-svr-base /include 目录(默认位置)中的所有文件
仅在编写程序以使用所说明的 API 来与 Messaging Server 集成时,以下文件才可用作参考:
msg-svr-base/examples/meauthsdk/
msg-svr-base/examples/tpauthsdk/
msg-svr-base/examples/mtasdk/
