I'm not sure about what you are seeing but here is one possibility. Normally there is a "spam delay" of about 10 minutes if the From: address does not match a subscriber. I think the idea is to be able to gather information on mail items going to more than one list or server and trigger a response within the 10 minute "cooling off period". You can set this for a list with the Loopcheck= Spam-Delay(mm) where mm is the number of minutes. It can be set to 0 for special cases but then you defeat the idea of being able to gather information and react to incoming spam notices. Marty
