- Plesk 12.5 for Linux
- Plesk Onyx for Linux
Note: This article has the reference to the issue with the fix available:
- #PPPM-5114 "Mailbox size was reported incorrectly if the directory storing the mailbox data was stored on a partition with a specific file system (e.g. xfs)."
- Plesk Onyx Update 6 14 November 2016 (Linux)
The usage of mailbox space differs between Plesk and mailbox directory on a server.
In Plesk > Subscriptions > example.com > Mail tab mail Usage shows 100MB.
But on the server the mailbox directory size is:
# du -schl /var/qmail/mailnames/example.com
Refreshing mail usage by clicking Refresh Usage Stats at Plesk > Subscriptions > example.com > "Mail" tab does not solve the issue.
This is Plesk bug with ID #PPPM-5114 that was fixed in Plesk Onyx 17.0 Update #6.
Upgrade to the latest version using Plesk Autoinstaller.
