    Hello everyone!
    Sorry if this question was asked.
    Discovered an unpleasant phenomenon. When the mail quota is exceeded, a notification letter comes only in one mailbox. Although, as it turned out, the quota was exceeded for many. Is this a mistake or is it supposed to be?
    I would also very much like to have a setting in which a notification about reaching a certain limit of cats would be sent to the culprit in the box.
    Now this is done using dovecot, but the letter is sent only once and the user often does not take action.
    Thank you.

    I have been using ISPconfig for over 5 years now. Really like. Thanks for your hard work!

    What have you configured in ISPConfig Panel | System | Server Config | Mail |
    in the "Send quota ..." settings?
    More info in ISPConfig Manual.

    Mailbox quota statistics - yes
    Send quota warnings to admin - yes
    Send quota warnings to client - yes
    Send quota warning each X days - 1 day
    Send quota ok message to client - yes

    Maybe this is important.
    I don't have a single client. I only use ISPConfig as my mail server.

    How have you verified the quota notice is sent only once?

    Checked on a test mailbox.
    /etc/dovecot/dovecot.conf
    Code:
    ...
    plugin {
      quota = dict:user::file:/var/vmail/%d/%n/.quotausage
    
      # no longer needed, as 'sieve' is in userdb extra fields:
      sieve=/var/vmail/%d/%n/.sieve
    
      sieve_before=/var/vmail/%d/%n/.ispconfig-before.sieve
      sieve_after=/var/vmail/%d/%n/.ispconfig.sieve
      sieve_max_script_size = 2M
      sieve_max_actions = 100
      sieve_max_redirects = 25
      quota_warning = storage=95%% quota-warning 95 %u
      quota_warning2 = storage=90%% quota-warning 90 %u
    }
    service quota-warning {
      executable = script /usr/local/bin/quota-warning.sh
      user = vmail
      unix_listener quota-warning {
      user = vmail
      }
    }
    ...
    
    Messages from dovecot are only sent when crossing the 90% and 95% threshold

    From a (very) quick look at the code, the notifications which ISPConfig sends (as opposed to the custom dovecot notifications you have setup on your server) send to the client's email address, and/or the server admin's email address, they do not send directly to individual mailboxes.
    That is the behavior described at https://doc.dovecot.org/configuration_manual/quota/, so you would have to set something else up to re-scan for over-quota mailboxes and send further notifications.
