Scott, I would hope that it wasn't just us that was seeing this problem. If anyone else is seeing the same problem with the lists of the domain names that I mentioned (or are seeing the opposite), I would appreciate the feedback. We haven't had any connectivity issues that I am aware of, other than momentary restarts of the SMTP service and an occasional reboot during security patch upgrades.
To make it a bit more convincing to me that this is not accidental behavior, these companies send mailings to numerous subscribers of ours on a number of different domains. No matter what domain it is, they always target the secondary MX. If we had a third MX record of lowest priority, I would bet dollars to doughnuts that they would be targeting that one instead. Unfortunately, I don't have a spare third network to test this theory on at the moment. :-) FYI, none of these sites are being bounced to the secondary because they are blocked by our primary server, as we maintain the same blocking lists on both servers.
