My recipe doesn't look at the subject line. It looks at the message body to 
see that certain typical keywords are present.

The idea is good, but I don't think that would have killed the spam on the 
mgetty mailing list. The spam on the mgetty mailing list was injected from 
usenet by the news <> mailing list gateway, and thus has valid ^Received 
lines.

I try to minimise domain-based spam filtering. They always come up with new 
names. I have a few simple heuristics that work quite well.

Anyway, this is becoming highly off topic. Let's take it to email or to the 
procmail mailing list or whatever.

With kind regards,
