Re: sendmail as a secondary MX

Alas, the old machine == the new machine. I've tried starting from virgin DF config files, but still no go. I've diffed the current configs to the old ones (yes, I did make a backup), and there are no differences that should be causing the problem. I'm perplexed.

Hmm, I think I may have stumbled onto something, but I haven't had time to really look at it yet. I added a domain I don't normally use into the relay-domains file, and restarted sendmail. Darn it if it didn't accept mail for that domain like a proper secondary. At the same time, it wouldn't treat mail for the other domains in the relay-domains file properly. The only difference I see off the bat is that the new domain isn't in reverse DNS for any of the IP addresses on the box.

Could it be that sendmail is seeing the domain names in rDNS for the servers IPs, and deciding that they are local, even if they are set in the relay-domains file?
