[afnog] Help!! Mails stuck in the hold queue

[Ses Blue]

Hello,
I have a mail server running on centos 5.5 with postfix, mailscanner, spamassassin and clamav.
This server is mostly used for relay and since yesterday morning, I have most of the emails being stuck in the hold queue (/var/spool/postfix/hold/). I don't know what caused this, no changes in config were done, unless it was caused by an update.
Could anyone out there please assist me?

Thanks.
