Mailbox disk usage per domain in Plesk

harmless rootPleskdebian, ubuntu
root@server
du -sh /var/qmail/mailnames/*/ 2>/dev/null | sort -rh | head -20

Sums up the mail directories per domain and lists the 20 largest. Plesk stores mailboxes under /var/qmail/mailnames/<domain>/<postfach> even with Postfix and Dovecot. Useful when disk space runs low and the webspaces are not the cause.

Note: For the mailboxes of a single domain, change the path to /var/qmail/mailnames/example.com/*/.
