Messages being delayed in the MailScanner hold queue

Basically, over the past couple weeks, we've been having several of our users report 1-2 hour delays in email. When checking the server logs, the SMTP headers of the delayed emails would show the time at which the emails got sent out. They would also indicate our server was receiving them not too much longer afterward. However, the spam filter would release the emails 1-2 hours later.
After parsing the maillog file in /var/log on the spamfilter, we determined that the delayed emails were getting dropped in the Mailscanner hold queue and remaining there (for hours) before getting requeued and getting sent out. We cannot find the log that reports what is going on when the emails get stuck in the mailscanner hold queue.
Has anyone seen this before? Is there a way to log for this issue?
