I should have said: "It doesn't help if you're trying to deliver mail
directly from your box". Joseph points out that so long as the name
resolves to the current dynamic IP, it should work. All I can say is
that when I was trying to do this, I had rejections from a few (overly
aggressive?) spam filters that didn't like the fact that the reverse DNS
didn't match the original name. I suspect such filters unnecessarily
reject a lot of people who have multiple aliases for their servers.
