The same error appears in logs if destination@example.com is disabled but its folder remains on the file system at
/var/qmail/mailnames/example.com/destination/and its size reached the mailbox limit set previously in Domains > example.com > Email Addresses > destination@example.com:
# du -sh /var/qmail/mailnames/example.com/destination/
105M /var/qmail/mailnames/example.com/destination/
Cause
The issue is caused by bug with ID #PPPM-10245, which is planned to be fixed in product future updates.
Resolution
As workaround,
- Log into Plesk
- Switch Mailbox back on for the email source@example.com (or for destination@example.com depends on whichever is limited) in Domains > eample.com > Email Addresses.
Note: After re-enabling the mailbox, either free space or increase the mailbox limit

This is a major major MAJOR issue on all our servers. Client email boxes that are OFF keep filling up and they suddenly stop receiving emails. We need a fix for this ASAP! We need a workaround that auto-clears messages from the mailboxes when they're off. A mailbox that is OFF should NOT STORE EMAILS. This is only a problem with the latest Plesk version and we have tons of accounts that use forwarding - we can't go in every few days and clear these out one by one on each system. Please fix or give us a real workaround like a cron job!
Plesk pointed me to this article to use to purge messages until this bug is fixed.
