[Mimedefang] Discarding fake MXs

[Ben Kamen]

Well, we do that for a reason... it sends spammers to the next 
(unreachable) MX point after failing to send spam to the primary. I used 
to use 127.0.0.1 - but people like SBC block incoming mail if the 
remote's have any MX's set like that (poo!)...

Oh well.
