Tough love: neither do our vanity domains (and yes, I have one too, and feel the same pain trying to get gmail to take mail). No one is going to pay someone to dig through our decades of mailing list activity trying to figure out whether to let a half dozen replies through.

This isn't the 1990's anymore, recipient domains aren't just homes to a few hundred undergraduates or a dozen programmers. Email hosts manage communication for hundreds of millions of customers.
