running a cpanel/whm server, whm 10.8.0, cpanel 10.9.0-S65.
having an odd quota issue wit mailboxes. I log into an account look at the pop accounts to see their usage/ quota. its showing me multiple MB of usage, whereas if i login as root and go to the mail directory, the users folder is a few hundred KB.
in fact, the total mail usage according to cpanel is over 27mb, whereas the mail folder is under 15- the entire account directory is about 16mb.
What is the mail format in your server now? Is it mbox or maildir. I have seen this issue when it is in maildir format.
Actually Cpanel takes the mail disk space value for a mail account from a file maildirsize inside that user folder.
And sometimes this file will not get properly updated and the Cpanel will show an incorrect disk space.
