Discard rather than reject unknown users

Hello,

A presumably infected machine is constantly banging on my machine with
tom@domain.com, dick@domain.com, harry@domain.com etc. in the hope of
finding a valid recipient.

I would like to discard rather than reject such a mail in the hope that
thinking a user has been found the infected machine will turns its sights
elsewhere (very likely this is wishful thinking).

In a world without spammers and viri, it makes no sense to do what I want to
do, i.e. pretend a message has been accepted,but I'm getting desperate...

I use iptables to do that. Drop all connections from such hosts.

It's wishful thinking.

With spammers it's also without sense. It's cheaper to send 550 than to
accept DATA. Spammers like addresses which they can send DATA. So they
wuold send You more and more every week ;)

I happen to be using Freebsd so I've just started to use ipfw instead, but
thanks for putting me on the right track!
