Working with Mailboxes (Directory tab)
You can manage users' mailboxes by setting limits on mailbox size and message count, and by deleting messages older than a specified date.
Note that IMail Server does not automatically create the mailbox files for users when the user is created. Mailboxes are not created until the first time the user receives mail or accesses his or her mailbox with a POP3 client. This prevents the creation of user files for users who never use IMail Server. Certain settings, such as mail forwarding, vacation processing, delivery rules, and information manager auto-responses cannot be made until a user's mailbox files exist.
To view mailbox directories and set limits:
- In the left panel, expand a mail host and Users folder, and then select a user. The user properties appear in the right panel.
- Click the Directory tab.
- You can view or change the following options:
- User Directory. The user's directory name in the IMail user database. You cannot edit this.
- Max. Mailbox Size. This is the maximum size allowed, for all mailboxes, in the user's account. If new mail will cause the total size to exceed this maximum, the mail is returned to the sender. Enter zero to use the host defaults; if the host default is also zero, the mailbox size is unlimited. For more information about host defaults, see "Setting Defaults for New Users" and "Additional Host Settings".
- Max. Mailbox Msgs. This is the total number of messages for each mailbox allowed for the user's mail account. If new mail, sent to a mailbox, would cause this maximum to be exceeded, the mail is returned to the sender. Enter zero to use the host defaults; if the host default is also set to zero, the mail box size is unlimited. For more information about host defaults, see "Setting Defaults for New Users" and "Additional Host Settings".
- Total Size (information only). The current total size (in bytes) of all mailboxes in the user's account.
- Total Msgs (information only). The current total number of messages in all mailboxes in the user's account.
- Files (information only). Total number of files in user's account.
- Click Apply to save any changes.
The Directory tab also lists all mailboxes (.mbx) in the user's directory on the IMail Server. For each mailbox, the list shows the.mbx file name, the size (in bytes), the number of messages it contains, and the last modified and first modified dates. You can delete or rename mailboxes, delete messages by date, or refresh the mailbox list information. To use the mailbox functions, select one of the following from the right-mouse menu:
- Delete File. Deletes the currently selected mailbox.
- Delete Msg's by Date. Automatically deletes message from the mailbox according to a specified date or age (number of days).
- Rename File. Displays a dialog box in which you can enter a new name for the mailbox.
- Refresh. Refreshes the list of mailboxes.
Combining Mailbox Names with User IDs
When addressing mail to a user, a mailbox name can be appended to the user ID by using the mailbox delimiter, which by default is a hyphen. For example:email@example.com
The mailbox name cannot contain hyphens. If a user ID contains a hyphen, IMail Server will check to see if it is a valid user ID. If it is not a user ID, the characters following the hyphen are interpreted as a mailbox name.
If the mailbox name does not exist, it is created on the IMail Server system (but not on the user's system). This is the only method an administrator can use to create user mailboxes. For more information, see "Advanced Options".
Users with POP3 mail clients can access alternate mailboxes using the userid-mailbox convention when they log on; for example, the user in the example above could log on as dave-music. Note, however, that only one POP3 mailbox can be accessed at a time.
If a user logs in with an IMAP4 client or with Web Messaging, the mailboxes will be displayed in the list of available mailboxes.
