You may have been right then, Rob - if you recently posted about having the exact same config I was thinking that that was Edinilson (I no longer have that email - oops) so that would make possibly three with this problem. He posted about this also, so I think I must be mixing you two up a bit.
It sounds like what you are doing should help get to the bottom of it ... As Davide points out, though, it must be something either unrelated (or maybe indirectly related) to XMail since so few seem to have it. My suspicion is still that it isWindows specific, possibly Win 2000 specific, and that it has to do with some interaction between that XMail binary and DNS. But I can't test it easily (it would take a gun to my head to get me to set up a Win 2000 server at this point). Francis and Edinilson seem to only have the problem with Hotmail and Yahoo, so that is also strange that you have it with many domains rather than just those two. Rob, are you outdide the U.S.? Edinilson, are you seeing the problem with Windows 2000 also or with some other OS? What is your config since seem to have confused Robs with yours?
