*URGENT* Major mail issues

[kcackler]

We are having some serious mail issues here right now with a single domain name (As far as I know, anyway)

For some reason, we are unable to check any mail on a single domain of ours, call it domain.com. We have deleted the account and recreated it to no success. When we attempt to log in (Through squirrelmail), we are shown:

ERROR: Connection dropped by IMAP server.


When this happens, the maillog has

I've run the fix_permissions email script but it did not fix anything. Any help is very much appreciated, as I have a sneaking suspicion that this problem is affecting more than just this one account.

If you need any additional information, just let me know.

OK, a little more info.

I SSH'd to the imap directory for the domain in question and ls -lh the contents. I saw that the imap folder for the user was owned by root:root - So I chown user:mail directory and am given the following error message:

chown: changing ownership of `user': Disk quota exceeded

I don't get what the issue is, because the 'user' email account has an unlimited quota...The domain's account still has roughly 4GB of disk space available, and the server itself is nowhere near running out of space.

So this is obviously some sort of quota issue, but I've got no idea where to begin.

Your harddrive is probably too full.

Type:

df -h

OK, fixed the problem. I have got no idea what is going on here. I ran quota -s user, and saw that for some reason, the user's quota was WAY down from what it should have been, even though directadmin was still showing the proper quota. So I went into DA, "Modified the User" (IE, just clicked the modify user button) and saved, and the quota was set back to its proper value.

I'm curious, though, as to how it got set to such a low value...
