Have you seen any of the files in the spool to see if there are real mails and not bouncing ones. Or perhaps to make sure your mailserver wasn't hikacked? Are those emails for or from your users? Make sure nobody is using your server to relay on and is sending large amounts of spam from there. That will explain why you have 37K messages in your spool
 
what is you daily volumen of emails?
 
Have you checked declude logs to see if they offer valuable information to determine what is going on.
 
Do you run Imail or Smartermail?
I'm running IMail.  I haven't noticed anything unusual in the logs, and I'm running two Postfix boxes in front of the IMail server to ward off distributed dictionary attacks, and their config has not changed.
