  • Warnings are enabled under Tools & Settings > Mail Server Settings > Enable mailbox quota warning

  • Dovecot configuration for quota warnings is missing:

    # ls -la /etc/dovecot/conf.d/20-plesk-quota-warning.conf
    ls: cannot access /etc/dovecot/conf.d/20-plesk-quota-warning.conf: No such file or directory

    Fixed in:

Resolution

Please consider updating your server:

Workaround

If update is not possible for some reason you may try the following:

  1. Connect to the server via SSH

  2. Create the missing file:

    # touch /etc/dovecot/conf.d/20-plesk-quota-warning.conf

  3. Edit file /etc/dovecot/conf.d/20-plesk-quota-warning.conf and add the following content:

    CONFIG_TEXT: #ATTENTION!
    #
    #DO NOT MODIFY THIS FILE BECAUSE IT WAS GENERATED AUTOMATICALLY,
    #SO ALL YOUR CHANGES WILL BE LOST THE NEXT TIME THE FILE IS GENERATED.

    plugin {
    quota_warning = storage=95%% quota-warning %u
    }

    service quota-warning {
    executable = script /usr/lib64/plesk-9.0/send-quota-warning
    user = popuser
    unix_listener quota-warning {
    user = popuser
    }
    }

    Hi Digital Connect,

    You may find errors or related entries in the /var/log/maillog. If you aren't able to find anything I suggest opening a ticket with our support department for further investigation

    Thanks Vladimir for your help, but the mails are still not being sent (the mailbox is at 98%). I've upgraded Plesk 17.5 to Obsidian 18.0.27 round about 2 weeks ago and installed the latest update today. Since the last 2 weeks i tried to disable and enable the setting, checked the Config (/etc/dovecot/conf.d/20-plesk-quota-warning.conf) but the warnings still not sent.

    If i just execute the script (/usr/lib/plesk-9.0/send-quota-warning) the mails sent without any problems..

    - When should the warnings normally be sent? Once a day at xx o'clock? If a new mail comes in?

    - Where can i check for errors? Maybe any Log file i can look for?

     

    Setup:

    - Ubuntu 16.04

    - Plesk 18.0.27

    - Mailserver: Postfix 3.4.8 + Dovecot 2.3.10

     

    Any help would be appreciated. Thanks in advance!
