Last execution output   Destination host '' (#1001), IP '' : Internal error: /usr/local/qmail/bin/setquota /usr/local/qmail/bin/setquota /usr/local/qmail/shared/mailnames/o/k/-1001/1001/Maildir/ 157286400S failed with code 1 saying: STDOUT: '' STDERR 'Failed to generate new maildir size name of '/usr/local/qmail/shared

  2. QMail quota-related binaries have incorrect permissions (see below).

Cause

QMail hosting was removed by another task from POA side or folders/permissions were manually removed.

Resolution

Following resolutions correspond to the symptoms above.

  1. Recreate the missing directories on the QMail server:

    # pwd
/usr/local/qmail/shared/mailnames/o/k/-1001/1001/Maildir
# mkdir mailfolder
# mkdir new
# mkdir cur
# mkdir tmp
# ls -ld *
drwxr-xr-x  2 root root 4096 Jul 15 17:27 cur
drwxr-xr-x  2 root root 4096 Jul 15 17:27 mailfolder
drwxr-xr-x  2 root root 4096 Jul 15 17:27 new
drwxr-xr-x  2 root root 4096 Jul 15 17:27 tmp
# chmod -R 700 *
# chown -R mailnames:qmail /usr/local/qmail/shared/mailnames/o/k/-1001/1001/Maildir/

  2. Make sure that setquota and checkquota binaries have proper ownership, fix it if needed:

    chown mailnames:qmail /usr/local/qmail/bin/setquota
chown mailnames:qmail /usr/local/qmail/bin/checkquota
chmod +s /usr/local/qmail/bin/setquota
chmod +s /usr/local/qmail/bin/checkquota
chmod g-s /usr/local/qmail/bin/checkquota
