These release notes contain important information about Netscape Messaging Server 4.15. Please read these notes before using the product.
Messaging Server 4.15 is available for the following platforms (refer to the Messaging Server Tuning Guide for required and recommended patches):
For Messenger Express access, Messaging Server 4.15 requires a Javascript-enabled browser.
The server is compatible with Netscape Navigator 3.x and 4.x, and Internet Explorer 3.02 and above. These browsers support Javascript and therefore will support Messenger Express access to Netscape Messaging Server 4.15. For optimal performance, Netscape recommends using the following browsers:
Use of this product is subject to the terms detailed in the license agreement accompanying it. For information on installing Netscape Messaging Server 4.15, see http://home.netscape.com/eng/server/messaging/4.1/install/contents.htm.
These release notes contain the following sections:
Netscape Messaging Server 4.15 enables ESPs and ISPs to quickly build business-grade messaging services for conducting communication and commerce with entire communities of employees, partners, suppliers, and customers. New features of Messaging Server 4.15 include:
Messaging Server 4.15 includes the following limitations and considerations: (See also Potential Problems and Solutions later in this document for other issues that might affect product capability or use.)
Install Messaging Server Export version 4.15 with Directory Server Export version (which comes packaged with Netscape Messaging Server 4.15). Or, install Messaging Server and Directory Server in separate server roots.
This warning message is harmless and does not affect the installation in any way.
If anonymous search is not available on the User and Groups Directory Server, then during installation the DN for the User/Groups Administrator should be used, not the user ID for the User/Groups Administrator.
Do not use double-byte characters in the BaseDN.
If you attempt to do this, the setup program displays a misleading error message and you will not be able to continue with the installation.
To obtain Netscape Console for platforms other than the installed platform, you'll need to obtain the appropriate platform version of Netscape Console by visiting http://home.netscape.com/eng/server/console/.
If this value is set too high, the system could hang and you would receive a "Virtual Memory Low" error message.
The numerical value that is entered is converted to the maximum integer value without warning.
The workarounds for this limitation are:
All Netscape Console Java environments must be shut down before running uninstall. Close and exit all instances of the Netscape Console before running uninstall. Be sure there are no Netscape Console instances running on remote machines.
If you encounter this problem, contact Technical Support.
This is normal. On Linux, threads within a process show up the same as processes under ps or top. There is really only one daemon with many threads. The exact number of threads depends on configuration and load.
If the server is installed in /usr/netscape/server4, the setup steps for C-shell users are listed below.
For running the GUI:
cd /usr/netscape/server4/jmailstone ../bin/base/jre/bin/jre -green -classpath \ ./JMailstone.jar:../bin/base/jre/lib/rt.jar JMailstone
For running the client:
cd /usr/netscape/server4/jmailstone ../bin/base/jre/bin/jre -green -classpath \ ./JMailstone.jar:../bin/base/jre/lib/rt.jar JMailclient
If you encounter this problem, contact Technical Support.
If the server process terminates unexpectedly, shut down all Messaging Server processes before restarting the server. Otherwise, the remaining processes might stop responding while waiting for locks held by the terminated process.
When this occurs, the message is deferred to a mailing list, but delivery of the message fails and an error message is sent to the postmaster.
The admin account is reserved and it is not recommended that you create such an account for Messenger Express access.
The Folders screen is blank.
If you elect to turn the cache on (for performance reasons), then you must restart all the services on the server to make the deletion of a user(s) effective.
If not, then turn off the cache for good by setting the service.authcachettl to zero and restarting all the services on the server.
If you type some text before the link, then the message can be viewed without any problems.
SNMP cannot be used on HP-UX 9000/8000 systems.
The amount of time it takes for the changes to propagate to the replicas depends on the replication schedule for the Directory Server.
When the MTA insists on authentication, Messenger Express gives up and drops the message without forwarding any type of error message.
To avoid this problem, rename the folder as appropriate before moving any users.
Note that the Messaging Server's imapd itself does not exhibit this problem; it shows the proper behavior and accepts the login.
This is due to Outlook Express incorrectly using multiple connections to the same mailbox.
There is no warning or dialog box to inform you of this fact.
Creating a suspend file and suspending programs works properly; however, once you remove the suspend file, program delivery does not work.
Do not delete alternate queues that still contain messages.
Netscape supports the XSERVER private extension for authenticating message submissions. Reconstructing a mailbox causes all of the authenticated sender information to be discarded.
The reconstruct -m command corrects an inconsistent message store.
The program delivery option will not work with shells that are not considered valid. On UNIX, the /etc/shells file contains the path for all valid shells. If the file is missing or empty, the following are valid login shells for the user to which the message is addressed:
For more information about program delivery, see the Messaging Server Administrator's Guide.
If the user is already over quota, the limit will also take effect when the user logs in. This means a user might still receive "over quota" messages until the user receives a new message or until the user logs off and logs in again. You can fix this problem by sending mail to the user after you reset the quota limit.
Most SMTP configuration settings require server restart; most POP, IMAP, and HTTP settings do not.
If you have questions about a particular configuration setting, contact Technical Support.
When you retrieve messages using Collect External Mail you may get a JavaScript error POP3 Communication failure and then get the messages.
The following section details the known problems and solutions for the Messaging Server 4.15 release. If a bug-report number follows the problem, please use that number when communicating with Technical Support concerning the problem.
See also the previous section, Known Limitations and Considerations, and the following section, Corrections to the Documentation, for other issues that might affect product capability or use.
These messages can be safely ignored.
Solution: By default, SSL is enabled for all services. To disable SSL without generating any error messages, use the following command:
configutil service.smtp.sslusessl no
Solution: If you install Messaging Server on the same Unix machine more than once, make sure the /etc/nsserver.cfg file contains, on the first line, the <server-root> of the Messaging Server you will be using.
If you have multiple queues, the uninstall process will remove the default queue, but not alternate queues. If you have multiple partitions, the uninstall process will remove the primary partition, but not subpartitions.
Solution: You will need to delete any alternate queues or subpartitions manually.
Solution: You might need to add an ACI for the Messenger Express administrator to the LDAP user/group DN entry. For more information, contact Technical Support.
Solution: You will need to save the 3.x information and re-create the entries for Messaging Server 4.15.
Solution: You will need to save the 3.x information and re-create the entries for Messaging Server 4.15.
Solution: If you want to create a custom DN for the end-user administrator, you must create these entries manually before the installation. You must create the end-user administrator group DN with the common name Enduser Administrators ("cn=Enduser Administrators"). You can create the end-user administrator user DN using any uid.
The Messaging Server properly stops all dependent services before stopping the SNMP service, but if the Directory Server is installed on the same machine, it will attempt to restart the SNMP service, which causes the installation to hang.
Solution: Manually stop the SNMP service before installing the Messaging Server and Directory Server on a Windows NT system. Otherwise, you can also install the Directory Server on a different system (recommended to avoid resource contention).
This message may appear even though the first port tested is genuinely not in use.
Solution: Re-enter the port number and it will be accepted the second time. If the install still reports the port is in use, then there is something active on the port.
Solution: Upgrade to glibc 2.1.2.
The message is deferred, but then there is no way to delete the deferred mail because it does not appear in the Netscape Console.
Solution: Manually create a .temporary directory in the primary store partition of the server.
Solution: Create these accounts on the Directory Server using the Netscape Console or the MigrateUnixSpool utility. The messaging server does not consult /etc/passwd for local accounts.
Solution: Either use a different window manager, or run startconsole with the -x,nologo parameter. For example:
<server-root>/startconsole -x,nologo
Solution: Edit /etc/nsswitch.conf to search DNS before searching NIS. Change the following line:
hosts: files nisplus nis dnsto:
hosts: files dns nisplus nis
Solution: Change the service.pop.numprocesses, server.imap.numprocesses, and service.http.numprocesses back to their default value of one (1).
The Directory Server holds the installation information for the Messaging Server. During an upgrade, the Directory Server is stopped and is unavailable to the installer.
Solution: To upgrade both servers, simply upgrade the Directory Server and the Messaging Server seperately.
Solution: Use the directory manager account and password instead. At this prompt:
User Directory Admin ID or DN: [admin]:
Enter:
cn=directory manager
Solution: Set the NS_NLS_DATADIRECTORY variable:
Solution: In the /etc/NscpMsg script, set the timezone (TZ) for Messaging Server by adding the following line after the LANG= variable:
export TZ=GMT-8
If you include a back-slash character (\) in an over-quota message, Messaging Server cannot parse the message and will not deliver the message to the user.
Solution: When specifying an over-quota message, do not use a back-slash character (\) in the message.
Solution: You can correct this problem by changing the line in the certmap.conf file from:
#default:FilterComps e, uid, ...to:
#default:FilterComps mail, uid, ...
Please note the following corrections to the Messaging Server 4.15 documentation:
On the CD, the Messaging Server 4.15 bits are already untar'd; therefore, there is no need to untar them as described in the Installation Guide.
The MTA looks up the language to be used when it performs international functionality as explained in the Administration Guide.
A new configurable parameter, local.service.smtp.sitelanguageonly, can be set to yes to disable the MTA language lookup capability so that it sticks to the value defined by gen.sitelanguage. This might be preferable if you want to automatically see generated messages in a particular language.
The instructions read as follows:
Localization. To localize the user interface, copy mail-en.html to a new file named mail-xx.html, where xx is the two letter abbreviation for a specific language. Translate all the string values associated with the i18n array elements. To localize the online help, modify the help.html file.
Instead, the instructions should be:
Localization. The <server-root>/msg-<instance>/html directory contains a directory for each language. Contained within each language directory is a copy of the i18n.js file. This file contains all the string values associated with the i18n array elements. Replace the string pair with the relevant language. To localize the online help, modify the help.html file.
