  • Plesk 12.0 for Linux
  • Plesk 11.5 for Linux


  1. QMail mailserver is installed on the server. Directory /usr/local/psa/handlers/spool is constantly filled up with mail messages which are not removed automatically, but they are supposed to.

  2. Plesk mchk (/usr/local/psa/admin/sbin/mchk) utility does not help.


Software issue #PPPM-1766 was confirmed and was fixed in microupdate #8 for Plesk 12: 12.0.18 MU#8


If update is not possible in your case you could use one of following workarounds:

  • Replace file /var/qmail/bin/qmail-queue with custom fix (attached)

  • Switch from QMail to Postfix

  • Create a cron task to clean up spool directory periodically.
