The drop in list traffic yesterday was my fault. The problem was on a system unrelated to the classiccmp server, but it only affected the classiccmp server. I believe it would have impacted just over a day of traffic. Problem resolved, and my apologies. Details for the tech oriented: Our hosting service has two front end mail processors (mx1/mx2) that do a lot of quick/basic checks before passing mail onto the backend mailbox servers. One of them had an issue and had to be restored from a backup that was a couple weeks old. We don't normally think anything of that in this particular case, because the config files on a front end mx basically never change so any backup is good. Much to my chagrin, I didn't realize that the backup for mx2 was taken BEFORE switching the mail stream for classiccmp.org are equal preference, that means that about half the inbound mail for classiccmp.org was being directed to the old server which has pretty much been sliced up as things were migrated to the new server. Last night I changed mx2 to deliver to the correct/new classiccmp server (mx1 was already doing so), and that fixed the problem. Newbie mistake, my apologies. Best, J
