Hi, FWIW, that sounds very like the problem I was running into - taking ASSP out of the loop fixed the problem but I couldn't just stop spam scanning because we were (and are) getting hammered with junk. Looking at your log reminded me of one more thing that I did: I turned off TLS on ASSP and forced my mail server to stop advertising TLS, or whatever it does to indicate that TLS is available. Yeah, I did a bunch of things in my haste to get my email back to normal. If I had the time, I would have been more systematic, but when reps are complaining that they can't get customer orders because of email problems it doesn't take long for higher management to start poking around. I'm just relieved I "fixed" the problem, whatever it was. I'm currently in "if it ain't broke, don't fix it" mode, so I can't give you much more help than this. Good luck. -- Edmond Inomoto
