Eh, you don't want to put this information into a public database. Officially, for privacy reasons. Unofficially, to create a barrier to market entry.
Right; I was not seriously suggesting that the DNS was the right spot for it. I am seriously suggesting that a redirect mechanism -- perhaps the email equivalent of HTPP's 301/302 -- would be worth considering. Then, of course, there's problem of upgrading the $\aleph_0$ mail senders out there to comply... --Steve Bellovin, http://www.cs.columbia.edu/~smb
