To do that, it'd have to do reverse lookup and an MX query..... and
then another query on the domains mail server itself to verify the
address. The problem with this is, most of the spam of late, is from
valid e-mail address's.... it's just the senders that don't actually
know it's being sent (the recent Blaster, Sobig etc etc worms being a
prime example)
Looks like a primative form of a challenge response system.
There was a bug debate in grc.spam recently about whether it's a good
idea.
