This is done with default canned rule.  Most of the time spamy works
correctly but it somehow decides to eat everything in sight. I have looked
in the queues at the msgs and found nothing strange about them or they are
cc'ed to 5-10 people here.  I can't keep the server running for any length
of time because it keeps doing the above top output. Also my sa is set to
768k message size

Any ideas
