[qmailtoaster] updated packages broke my qmail install

[slamp slamp]

I have centos 4.3. I used the upgrade script and hit yes for every package. I can't send/receive any e-mails. Please help!

Requested action aborted: error in processing
Server replied: 451 qq write error or disk full (#4.3.0)

I get the error when using squirrelmail on the server itself or any e-mail client. I ran queue_repair.py thinking the queue is damaged and I have plenty of space. (don't mind my partition scheme)
