Chapter 4 Managing Mail Users and Mailing Lists

This chapter explains how mail accounts and mailing lists are implemented in Messaging Server 4.0, and it describes how to use the Netscape Console interface to create and manage your users' mail accounts and mailing lists.

This chapter contains the following sections:


About Users and Groups for Messaging
Messaging Server 4.0 requires close integration with an LDAP directory service such as Netscape Directory Server. One reflection of this close integration is the manner in which mail accounts and mailing lists are implemented.

 Users and Mail Accounts

An LDAP user directory can contain a wide range of information about an organization's employees, members, clients, or other types of individuals that on one way or another "belong" to the organization. These individuals constitute the users of the organization. In the LDAP directory, the information about users is structured for efficient searching, with each user entry identified by a set of attributes. Directory attributes associated with a user can include name and other identification, division membership, job classification, physical location, name of manager and direct reports, access permission to various parts of the organization, preferences of various kinds, and so on.

In an organization with electronic messaging services, many if not all users hold mail accounts. For Messaging Server 4.0, mail-account information is not stored locally on the server; it is part of the LDAP user directory. The information for each mail account is stored as a particular set of attributes attached to a user's entry in the directory. To retrieve or modify information for a specific user's mail account, an administrator uses the Messaging Server interface to access that user's mail attributes in the directory.

 Groups and Mailing Lists

An LDAP user directory also can contain entries that represent collections of users. These directory groups can consist of a specific set of users or they can be rule-based, with membership defined by job classification or any other user attributes.

Groups can exist for a wide variety of purposes, and they have their own sets of attributes in the user directory. Groups may be used for information sharing in departments or on projects, for providing selective access to sensitive data, for discussion on shared interests, for disseminating company or division policy, and so on.

 Messaging Server 4.0 provides support for mailing lists, which can be thought of as group addresses (similar to sendmail aliases) with additional associated information (such as a set of access permissions for posting to the list). As with mail-account information, Messaging Server stores mailing-list information in the LDAP user directory rather than locally. The information is stored as a set of attributes belonging to a particular group. To retrieve or modify information for a specific mailing list, an administrator uses the Netscape Console interface to access the appropriate group's attributes in the user directory.

 A mailing list can exist as its own group in the directory, or mailing-list capability can be added to any existing directory group.

 Mail-Administration Features

You use the mail-administration portion of the Netscape Console interface to configure and administer the mail accounts and mailing lists hosted by your Messaging Server. These are the general tasks you can perform:

For any user in your user directory, you can

 For any group in your user directory, you can

 Subsequent sections in this chapter give detailed discussions of these administrative tasks. Before you can perform them, however, you must first enable the mail-administration interface, as described in the next section.

Note: For entry or manipulation of large numbers of mail accounts, it may be more efficient to use bulk methods than to use the Netscape Console interface described here. For more information, see the discussion on migration tools in Appendix A, Command-line Utilities, and Appendix C, sendmail Migration and Compatibility.


Managing Mail Users
Accessing Mail Users

This section describes how to get to the mail administration interface for your users. Because Messaging Server mail accounts are stored as attributes of user entries in an your enterprise's central LDAP user directory, managing mail accounts means accessing and modifying user entries in that directory.

Creating a New User

To create a new mail account, you create a new user in the directory. You must also install a mail account for that user; if you do not install the mail account, the mail-administration portion of Netscape Console is not available. (The full process of creating a user and specifying other kinds of user information is described in more detail in Managing Servers with Netscape Console).

To create a new mail user:

  1. In the Netscape Console main window, click the Users and Groups tab. The Users and Groups window opens.

  2. Select New User and click Create. After you select an organizational unit for the user, the Create User window opens (see Figure 4.1).

  3. Enter at least the required information to create the user entry, as noted in the Users and Groups chapter of Managing Servers with Netscape Console.

  4. Before closing the Create User window, click the Account tab. A list of installable products for the new user's account appears in the right pane (see Figure 4.2).

  5. Click the Mail Account Install box. The Mail tab becomes visible in the Create User window.

  6. Click on the Mail tab in the Create User window, then click the appropriate tab in the right pane to go to the desired form (see Figure 4.3).
    7. (These are the forms described in this chapter.)

  7. Enter your changes, then click OK at the bottom of the Create User window. This submits your entries and dismisses the Create User window.

    8. Note. Clicking OK at the bottom of any mail administration form submits all of the current mail configuration information entered into all of the mail administration forms. Make sure you complete all setup procedures in the relevant forms before clicking OK.

Figure 4.2 Create User window with Install Mail Account option

Figure 4.3 Create User window with mail account installed (Mail tab selected)

 Accessing an Existing User

To modify an existing mail account or to add a mail capabilities to an existing user, you access the appropriate user in the user directory and then add or modify that user's mail-account attributes.

To access mail information for an existing user:

  1. In the Netscape Console main window, click the Users and Groups tab.

  2. In the Users and Groups main window, Click Search or Advanced Search.

  3. Enter your search criteria (such as the user's last name) in the Search window, and perform the search of the user directory.

  4. Back in the Users and Groups main window, select a user from the search results and click Edit. The Edit Entry window opens.

  5. If the Mail tab is not visible in the Edit Entry window, do this:

  6. Click the Mail tab in the Edit Entry window, then click the appropriate tab in the right pane to go to the desired form.
    7. (These are the forms described in this chapter; they are identical to those you access through Create User window.)

  7. Enter your changes, then click OK at the bottom of the Edit Entry window. This submits your modifications and dismisses the Edit Entry window.
Specifying User Email Addresses

Before mail can be delivered successfully to a user, you must specify the mail addressing information for that user. This consists of the Messaging Server host name, the user's primary address, and any alternate addresses. The host name and primary address information is mandatory; alternate address information is optional.

To specify a user's mail addressing information:

  1. In Netscape Console, access the Create User or Edit Entry window, as described in Accessing Mail Users.

  2. Click the Mail tab.

  3. Click the Settings tab, if it is not already frontmost. The Settings form is displayed.

  4. (Required) Enter the Messaging Server hostname.

    5. This is the machine hosting the Messaging Server that will process this user's mail. This must be the fully-qualified domain name (FQDN) known to the Messaging Server on that machine.

  5. (Required) Enter the user's primary email address.

    6. This is the publicized address to which this user's mail is to be sent. There can be only one primary address for a user, which must be a valid, correctly formatted SMTP address conforming to RFC 821 specifications.

    If you want to implement hostname hiding (the host name in the user's address is not to be shown in the outgoing mail header) do not specify the host name in the Primary email address field.

  6. (Optional) If you want to add an address to the Alternate Address list, click Add to go to the Add Alternate Address window.

    7. An alternate address is essentially an alias for the user's primary address. You can use this feature, for example, to ensure proper delivery of frequently misspelled addresses (e.g., "Smith" as an alias for "Smythe"), or for host name hiding in outgoing mail headers. You can specify any number of alternate addresses for a particular user, as long as each address is unique. Messages arriving for any of these aliases are directed to the primary address.

    Enter the user's alternate address in the address field (you cannot enter more than one address each time you open this window).

    Click OK to add the address and dismiss the Add Alternate Address window.

    (See Add Alternate Address Window for a complete description of the contents of this window.)

  7. Click OK in the Settings form if this action completes all changes that you wish to make to this user's mail information. Otherwise, click other tabs to continue making entries in other forms.
See Mail Settings Tab for a complete description of the contents of this form.

Configuring Delivery Options

The Messaging Server supports three principal mail-delivery options that you can enable and configure, in any combination, for each user. You can provide regular POP/IMAP delivery, program delivery, and Unix delivery (for clients of a Unix Messaging Server host).

Messaging Server also provides an end-user HTML interface through which users can themselves enable and configure these options. The Netscape Console (administrator) interface and the HTML (user) interface both manipulate the same directory attributes; when opened, each shows the current settings, whether they were set by the administrator or by the user.

 To configure delivery options for a user:

  1. In Netscape Console, access the Create User or Edit Entry window, as described in Accessing Mail Users.

  2. Click the Mail tab.

  3. Click the Delivery tab. The Delivery Options form is displayed.

  4. Select the delivery method or methods you want to enable for this user:

  5. Click OK in the Delivery Options form if this action completes all changes that you wish to make to this user's mail information. Otherwise, click other tabs to continue making entries in other forms.
See Delivery Options Tab for a complete description of the contents of this form.

Specifying POP/IMAP Delivery

Specifying this option enables mail delivery to the user's regular POP3 or IMAP4 mailboxes. To enable POP/IMAP delivery for this user:

  1. Access the Delivery Options form.

  2. Check the POP/IMAP box, and click the Properties button to open the POP/IMAP Delivery window.

  3. Enter the nickname of message-store partition to which the user's messages are to be delivered and stored for processing. If you leave this field blank, the current primary partition is used. See Chapter 5, Managing the Message Store, for more information.

  4. Enter the storage limit, or disk quota, to be allotted to the user. The quota can be either unlimited (no maximum storage limit), or you can specify a limit (KB or MB). Unlimited is the default.

  5. Note the contents of the Access domain field. Access domains are domains from which this user is permitted to retrieve mail. If no access domains are specified in the Access domain field, this user can retrieve mail from any domain. Entries in this field can be either domain names or IP addresses.
    6. If you want to specify access domains, click Add next to the Access Domains field. The Add Access Domains window opens.

  6. Enter a domain name in the Access domain name field.

    7. You must enter only a single domain name each time you access the Add Access Domains window. You can enter either a regular domain name or an IP address. If you specify a domain that does not exist, or enter none, then you effectively block access for this user.

    See Add Access Domain Window for a complete description of the contents of this window.

  7. Click OK to add the domain to the list and dismiss the Add Access Domain window.
See POP/IMAP Delivery Window for a complete description of the contents of this window.

Specifying Program Delivery

Specifying this option provides a mechanism for forwarding messages to an external application for processing before delivery to the user.

Note: This section describes only how to make the program delivery option available to an individual user. You must first enable the program delivery module as a whole, which requires performing several other administrative tasks. See Appendix B, Program Delivery, for details.

To enable program delivery for this user:

  1. Access the Delivery Options form.

  2. Check the Program delivery box, and click the Properties button to open the Program Delivery window.

  3. Enter the external application command(s) to be used for processing this user's mail.

  4. Click OK to submit your entry and dismiss the Program Delivery window.
See Program Delivery Window for a complete description of the contents of this window.

Specifying Unix Delivery

Specifying this option selects Unix delivery for this user. The Unix delivery feature allows messages to be delivered to the user's designated Unix mailbox. Unix delivery is available only to users whose Messaging Server runs on a Unix host machine.

To enable Unix delivery for this user:

  1. Access the Delivery Options form.

  2. Check the Unix delivery box.

    3. Note: Beyond the steps shown here, providing Unix delivery to Messaging Server users naturally requires you to perform normal Unix mail administrative tasks.

Specifying Forwarding Addresses

The mail-forwarding feature of Messaging Server 4.0 enables a user's mail to be forwarded to another address instead of or in addition to the primary address for that user.

Messaging Server also provides an end-user HTML interface through which users can themselves specify forwarding addresses. The Netscape Console (administrator) interface and the HTML (user) interface both manipulate the same directory attributes; when opened, each shows the current settings, whether they were set by the administrator or by the user.

To specify forwarding-address information for a user:

  1. In Netscape Console, access the Create User or Edit Entry window, as described in Accessing Mail Users.

  2. Click the Mail tab.

  3. Click the Forwarding tab. The Mail Forwarding form is displayed.
    4. The Forwarding Address field in the form shows the current set of forwarding addresses, if any, for the user.

  4. To add a forwarding address, Click Add. The Add Forwarding Address window opens.

  5. Enter a forwarding address in the Forwarding address field.

  6. Click OK to add the address to the Forwarding address field in the Mail Forwarding form and dismiss the Add Forwarding Address window.
    7. (See Add Forwarding Address Window for a complete description of the contents of this window.)

  7. Click OK in the Forwarding Address form if this action completes all changes that you wish to make to this user's mail information. Otherwise, click other tabs to continue making entries in other forms.
See Mail Forwarding Tab for a complete description of the contents of this form.

Configuring Auto-Reply Settings

The auto-reply feature of Messaging Server 4.0 allows you to specify an automatic response to incoming mail for a user. You can specify three different auto-reply modes: echo mode, vacation mode, and auto-reply mode.

Messaging Server also provides an end-user HTML interface through which users can themselves enable and configure auto-reply settings. The Netscape Console (administrator) interface and the HTML (user) interface both manipulate the same directory attributes; when opened, each shows the current settings, whether they were set by the administrator or by the user.

 To enable an auto-reply service for a user:

  1. In Netscape Console, access the Create User or Edit Entry window, as described in Accessing Mail Users.

  2. Click the Mail tab.

  3. Click the Auto-Reply tab. The Auto-reply form is displayed.

  4. Select one of the auto-reply modes:
    5. Off: Disables auto-reply for this user.

    Echo: An automatic reply is sent for each received message and the received message appended as a MIME attachment to the reply. If you select this mode, you can enter a reply message in the Message field.

    Vacation: The first message received by this user from a given sender generates an automatic response; subsequent messages from that sender do not generate a response. If you select this mode, you can enter a reply message in the Message field.

    Auto-reply: Every incoming message received by the user generates the specified automatic response. (The received message is not attached to the reply.) If you select this mode, you can enter a reply message in the message field.

  5. If you have selected echo, vacation, or auto-reply mode, you can (optionally) specify the reply message to be returned to the sender.You can crate one message in each of several available languages (specified in the popup menu above the field).

  6. Click OK in the Auto-Reply form if this action completes all changes that you wish to make to this user's mail information. Otherwise, click other tabs to continue making entries in other forms.
See Auto-Reply Tab for a complete description of the contents of this form.


Managing Mailing Lists
Accessing Mailing Lists

This section describes how to get to the administration interface for your mailing lists. Because Messaging Server mailing lists are stored as attributes of group entries in an your enterprise's central LDAP user directory, managing mailing lists means accessing and modifying directory groups.

Creating a New Group

To create a new mailing list, you create a new group in the directory. You must also install a mail account for that group; if you do not install the mail account, the mail-administration portion of Netscape Console is not available. (The full process of creating a directory group and specifying other kinds of group information is described in more detail in Managing Servers with Netscape Console).

To create a new mailing list:

  1. In the Netscape Console main window, click the Users and Groups tab. The Users and Groups window opens.

  2. Select New Group and click Create. After you select an organizational unit for the group, the Create Group window opens (see Figure 4.4).

  3. Enter at least the required information to create the group entry, as noted in the Users and Groups chapter of Managing Servers with Netscape Console.
    4. Note: For mailing-list purposes, you do not have to add members through the Members tab of the Users and Groups interface:

  4. Before closing the Create Group window, click the Account tab. A list of installable products for the group account appears in the right pane.

  5. Click the Mail Account Install box. The Mail tab becomes visible in the Create Group window.

  6. Click on the Mail tab in the Create Group window, then click the appropriate tab in the right pane to go to the desired form (see Figure 4.5).
    7. (These are the forms described in this chapter.)

  7. Enter your changes, then click OK at the bottom of the Create Group window. This submits your entries and dismisses the Create Group window.

    8. Note. Clicking OK at the bottom of any mail administration form submits all of the current mail configuration information entered into all of the mail administration forms. Make sure you complete all setup procedures in the relevant forms before clicking OK.

Figure 4.5 Create Group window with mail account installed (Mail tab selected)

 Accessing an Existing Group

To modify an existing mailing list, or to add a mailing-list capabilities to an existing group, you access the appropriate group in the user directory and then add or modify it's mail-account attributes.

To access mailing-list information for an existing group:

  1. In the Netscape Console main window, click the Users and Groups tab.

  2. In the Users and Groups main window, Click Search or Advanced Search.

  3. Enter your search criteria (such as the group's name) in the Search window, and perform the search of the user directory.

  4. Back in the Users and Groups main window, select a group from the search results and click Edit. The Edit Entry window opens.

  5. If the Mail tab is not visible in the Edit Entry window, do this:

  6. Click the Mail tab in the Edit Entry window, then click the appropriate tab in the right pane to go to the desired form.
    7. (These are the forms described in this chapter; they are identical to those you access through Create Group window.)

  7. Enter your changes, then click OK at the bottom of the Edit Entry window. This submits your modifications and dismisses the Edit Entry window.
Specifying General List Information

Before mail can be delivered successfully to your mailing list, you must specify its mail-addressing information. This consists of the primary address for the group, any alternate addresses you want to accept as aliases to the primary address, plus optional descriptive information about the purpose, attributes, members, and so on, for the mailing list. This description is for informational purposes only; it is not used by the Messaging Server.

To specify general mailing-list information:

  1. In Netscape Console, access the Create Group or Edit Entry window, as described in Accessing Mailing Lists.

  2. Click the Mail tab.

  3. Click the General tab, if it is not already frontmost. The Mail General form is displayed.

  4. (Required) Enter the mailing list's primary email address.

    5. This is the publicized address to which this list's mail is to be delivered. There can be only one primary address for a list. It must be a correctly- formatted SMTP address that conforms to RFC 821 specifications.

  5. (Optional) Click Add below the "Alternative email addresses" field to specify an alternate address for the mailing list. The Add Alternate Address window opens.

  6. (Optional) Enter the email address of a person, if any, to whom errors in posting messages to the list should be sent.

  7. (Optional) Click Add below the "Mail list owners" field to specify one or more owners of this list.
    8. The Add List Owners window opens. Click either DN or email address, enter the information in the window, then click OK to add the owner to the list and dismiss the window.

  8. (Optional) Enter the host name of the machine hosting this mailing list.
    9. If the Primary email address field for this mailing list includes a host name, you can leave this field blank. If you implement host-name hiding by having no host name in the primary email address, specify the host name in this field.

  9. (Optional) Enter a text description of the purpose or nature of the mailing list.

  10. (Optional) Enter a URL to an HTML page providing additional information about the mailing list. This is for informational purposes only; the URL is not used by Messaging Server.

  11. Click OK in the Mail General form if this action completes all changes that you wish to make to this mailing list. Otherwise, click other tabs to continue making entries in other forms.
See Mail General Tab for a complete description of the contents of this window.

Specifying List Members

You can add members to your mailing list by using one or both of the following methods:

The mailing-list members described here are called email-only members in the Users and Groups interface of Netscape Console, because they have group privileges limited to those provided by the mailing-list component of the group. "Regular" group members, which you add using a different part of the interface (described in Managing Servers with Netscape Console), may have additional privileges or responsibilities beyond those of mailing-list members.

 Defining Dynamic Membership Criteria

Dynamic criteria consist of LDAP Search URLs that are used as filters in searching the user directory for determining membership. This mechanism is dynamic in that, when a message arrives for the group, the individuals that receive it are determined by a directory search rather than by consulting a static list of names. You can thus create and maintain very large or complex groups without having to track each member explicitly.

LDAP Search filters must be formatted in LDAP URL syntax. For more detailed information on constructing LDAP filters, see the users and groups chapter of Managing Servers with Netscape Console. See also the Directory Server documentation and RFC 1959.

 An LDAP URL has the following syntax:

 ldap://hostname:port/base_dn?attributes?scope?filter

 where the elements of the URL have the following meanings:
Element
Description
hostname
Hostname of the Directory Server.
port
Port number for the LDAP server. If no port is specified, the standard LDAP port (389) is used.
base_dn
Distinguished name of an entry in the directory, to be used as the search base. This component is required.
attributes
The attributes to be returned. If no attributes are specified, all attributes are returned.
scope
Scope of search:
filter
Search filter to apply to entries within specified scope of search. If no filter is specified, (objectclass=*) is used.

The following is an example of an LDAP Search URL that filters for users who have sunnyvale as their mail host:

 
ldap:///o=Airius Corp,c=US??sub?(&(mailHost=sunnyvale.ace.com)\ 
(objectClass=inetOrgPerson))
This URL filters for users who are members of the organization (o) of Airius, have the country (c) attribute of US, and a mail host (mailHost) of sunnyvale. The objectClass attribute defines the type of entry for which to search, in this case inetOrgPerson.

 Note that, by default, group names found by a search are ignored; that is, their members are not considered to be part the group defined by the search.

 As noted in the next section, Netscape Console provides a template window (the Construct LDAP Search URL window) that you can use as an aid in building a search URL.

Adding Mailing-List Members

To add (email-only) members to a mailing list:

  1. In Netscape Console, access the Create Group or Edit Entry window, as described in Accessing Mailing Lists.

  2. Click the Mail tab.

  3. Click the Mail List Members tab. The Mail List Members form is displayed.

  4. (Optional) To specify an LDAP Search URL for determining membership, click Add below the "Dynamic criteria for email-only membership" field. The Add Dynamic Criterion window opens.

  5. (Optional) To explicitly add an individual member to the mailing list, click Add below the "Members with Email Only Membership" field. The Add Email-Only Member window opens.

  6. Click OK in the Mail List Members form if this action completes all changes that you wish to make to this mailing list. Otherwise, click other tabs to continue making entries in other forms.
See Mail List Members Tab for a complete description of the contents of this form.

Defining Message-Posting Restrictions

You can impose various kinds of restrictions on messages sent to a mailing list. You can define the set of people allowed to post messages, you can require authentication of senders, you can restrict where posted messages can come from, and you can limit the size of a posted message. Messages that violate the restrictions are rejected.

Note: Although these restrictions are useful for controlling several aspects of the incoming messages for a group, they are not intended to provide high-security access control.

To define message-posting restrictions for a group:

  1. In Netscape Console, access the Create Group or Edit Entry window, as described in Accessing Mailing Lists.

  2. Click the Mail tab.

  3. Click the Message Restrictions tab. The Message Restrictions form is displayed.

  4. (Optional) Define the allowed senders. Make one of the following choices:

  5. (Optional) Define the sender authentication policy. Make one of these choices:

  6. (Optional) Define the allowed sender domains, to restrict where senders can post messages from. Click Add below the Allowed sender domains field. The Add Allowed Sender Domain window opens. Enter a domain name, and click OK to add the domain to the list and dismiss the Add Allowed Sender Domain window.
    7. (See Add/Edit Allowed Sender Domain Window for a complete description of the contents of this window.)

  7. (Optional) Define the maximum permitted message size. Enter the size (in bytes) into the field.

  8. Click OK in the Message Restrictions form if this action completes all changes that you wish to make to this mailing list. Otherwise, click other tabs to continue making entries in other forms.
See Message Restrictions Tab for a complete description of the contents of this form.

Defining Message-Rejection Actions

You can specify that Messaging Server automatically execute certain notification actions when messages to your mailing list are rejected because they violate the list's message-posting restrictions.

This feature lets you to define the action to be executed upon rejection of a mail message, and to specify group moderators. The actions that the server can take include notification to a moderator and reply to the sender (with or without appending the original message).

 To define message-rejection actions for a mailing list:

  1. In Netscape Console, access the Create Group or Edit Entry window, as described in Accessing Mailing Lists.

  2. Click the Mail tab.

  3. Click the Message Reject Actions tab. The Message Reject Actions form is displayed.

  4. (Optional) To automatically forward rejected messages to moderators, check the "Send message to the moderator(s)" box.
    5. The moderator or moderators then decides how to process the message. That may include approving the message and forwarding it back to the list (perhaps with a password). By checking this box you can thus institute a fully moderated mailing list.

  5. (Optional) To automatically reply to rejected messages, check the "Send the following reply to the sender" box.

  6. Click OK in the Message Reject Actions form if this action completes all changes that you wish to make to this mailing list. Otherwise, click other tabs to continue making entries in other forms.
See Message Reject Actions Tab for a complete description of the contents of that form.


Interface Reference: Managing Mail Users
This section describes the Netscape Console interface elements that allow you to configure and manage the mail-related components of the user information stored in the LDAP user directory. See Managing Servers With Netscape Console for general information on using Netscape Console to manage Messaging Server and other servers. See Directory Server Administrator's Guide for information on LDAP, the user directory, and other user information stored in the directory.

All users in the user directory matching any criteria defined here are considered members of this mailing list. Applying dynamic membership criteria saves you the effort of specifying each member explicitly when creating a mailing list.

 Click the Add, Edit, or Delete buttons to modify the information in this field.

 Add. Click this button to open a window (see Add/Edit Dynamic Criterion Window) that lets you add a dynamic membership criterion (in the form of an LDAP URL) to the "Dynamic criteria for email-only membership" field.
