Mail somehow bypassing spamassassin entirely showing up in my Inbox

[Arias Hung]

I've been having the issue lately of at least a few mails a day somehow bypassing spamassassin via procmail entirely and showing up in my inbox.

Can someone suggest how I might even go about troubleshooting this?  Perhaps
this is better asked on the procmail list, although I thought I'd give it a shot
here first since I'm subbed.

Thanks in advanced to whoever is kind enough to reply.

Sometimes its more like a flood which forces me to inevitably to forward my entire inbox through procmail through formail again to filter its spam.
