14.2.6. Mail quota#

The size of the users’ mailboxes can be restricted via the mail quota. When this is attained, no further emails can be accepted for the mailbox by the mail server until the user deletes old mails from their account.

The limit is specified in megabytes in the Mail quota field under Advanced settings ‣ Mail. The default value is 0 and means that no limit is set. The multi edit mode of UMC modules can be used to assign a quota to multiple users at one time, see Editing objects.

The user can be warned once a specified portion of the mailbox is attained and then receives a message that their available storage space is almost full. The administrator can enter the threshold in percent and the messages subject and text:

  • The threshold for when the warning message should be issued can be configured in the Univention Configuration Registry Variable mail/dovecot/quota/warning/text, for example mail/dovecot/quota/warning/text/PERCENT=TEXT

    PERCENT must be a number between 0 and 100 without the percent sign.

    TEXT will be the content of the email. If the value TEXT contains the string $PERCENT, it will be replaced in the email with the value of the limit that has been exceeded.

    The value of the Univention Configuration Registry Variable mail/dovecot/quota/warning/subject will be used for the subject of the email.

  • When the mail server package is installed, a subject and two warning messages are automatically configured:

    • mail/dovecot/quota/warning/subject is set to Quota-Warning

    • mail/dovecot/quota/warning/text/80 is set to Your mailbox has filled up to over $PERCENT%.

    • mail/dovecot/quota/warning/text/95 is set to Attention: Your mailbox has already filled up to over $PERCENT%. Please delete some messages or contact the administrator.
