Unfortunately, Mailsite can't solve this. They come in from a valid address
and do HUNDREDS of queries for valid names on your server. Then they mail to
them later.

I wrote Sylvain at Vircom (VOPMail, uses the same engine that Mailsite does
and has improved it immensely and he says the only
way to deal with this is to have a server timeout after a certain number of
invalid requests. None of the mail servers do that out of the box right now.

I would still encourage people to configure their smtp servers properly with
inverse addressing. I personally think this is the way to go.
