The "I love you virus" .. and content based filtering

[Nicolas MONNET]

Lusers are stupid, and it's a shame that we have to do this, but ... to
stop the plague before things get too nasty, we need to filter that bloody
"I love you" worm. Is there any way to quickly (and dirtily) implement
that in qmail? I'm not looking for a permanent solution, just a quick
workaround that I'll get rid off later.
