Enabling Mail for Users
Once you have the mail server configured, you can start configuring your User's accounts to be able to send/receive email on your server. To do this, simply go to the Yast User Management module and edit any user you want to be able to receive mail.
Launching the "User Mail Parameters" Plugin and Adjusting the User's Mail Settings
The specific area you want to be in is the "Plug-Ins" tab of the User configuration screen and ensure that there is a checkbox beside the "Edit user mail parameters". You can also highlight that plugin and hit "Launch" to start the Mail Settings page for that user. Here you can define additional email addresses that you want the user to be able to receive mail for. This is useful if you host multiple Mail domains on your server.
Enabling Mail for Groups
Similar to enabling mail for specific Users, you can also enable mail for specific Groups. This has two benefits. First, you are able to create "Mailing Lists" by creating a new Group and adding the users to the group that you wish to receive the list's mail.
Enabling Group Email Options and Accessing Shared Mail Folders through Thunderbird
In addition to Mailing Lists, you can also utilize a "Shared Folder" for a specific Group by using the Group Mail Plugin. This allows the user to "subscribe" to the Group Folder within their Email Client, thus allowing all members of the Group to share all the email, documents, etc that are located within the IMAP folder. You may need to reference your Email Client's documentation to find out how to "subscribe" to shared IMAP folders.
Advanced Mail Configurations and Preventative Tasks
The Yast Mail Server module was created to make it somewhat easy to setup a Mail Server on Suse Linux Enterprise Server. There are many times where you will need to fine tune your server with options that are not available within the Mail Server Module. To further help you along, Suse includes quite a few options that you can adjust within the "/etc/sysconfig Editor" Yast module. However be aware that anything you adjust there can have adverse affects if you plan on continuing to use the Mail Server module.
To maintain your mail server, you should realize that the Cyrus IMAP server stores all of the it's files within the "/var/lib/imap" directory and all of the user's mail is stored in the "/var/spool/imap" directory, so ensure you backup these directories periodically. Also note that Suse Linux Enterprise Server utilizes scripts to automatically backup any databases that Cyrus needs to run properly, these backups are also found within the "/var/spool/imap" directory.
