A simple rule for IP1<>IP2

2002-09-08 04:23:59
Hi!

Looking at the SPAM messages that still pass my procmail file I often see they 
have such a "Received from" line in the header (for instance this one from a 
message that 
just came in):

Received: from 196.40.67.195 ([210.15.67.232])

or generic:

Received: from IP1 ([IP2])

where IP1<>IP2.

What would be the rule be to dump such messages to /dev/null?

I suppose this probably is more-less basic but I didn't find such a rule 
searching arround.

Thanks in advance,
