Well in that case, this is how it's been set up since I put up the IMail server. Then I'm back to not having an explanation as to why a certain percentage of outbound mail from my server gets rejected by the receiving mail server. > > >So let me get this straight--I should contact them, and tell them to fix the > >reverse lookup for 64.105.9.212 and have it point to my DNS server instead of > >theirs? > > You don't have to, since they have a reverse DNS entry for your IP.

I'm going to ask them to redirect the reverse lookup zone back down to my IP address of 64.105.9.212, at least temporarily to see if it affects the problem. If this isn't the problem, any other ideas as to what would cause outbound mail from my IMail server to get rejected?
