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
