Are you running a local caching name server either on your MX boxes or
somewhere on your LAN that the MX boxes can do nslookups to?

I had a similar issue, my /var/spool/mqueue.in would get backed up to
anywhere from 1 to 2 thousand messages.  After implementing the local
caching name server I have been good to go for the whole week so far.

Also, use Ugo's suggestions.
