Sorry Marc, but such messages are already catched by spamassassin...

Any good provider have already implemented rules to catch such messages.
I am ISP too, and my customers expect, that I catch this crap...

Messages marked as spam by  users  go  to  a  special  account  for  (if
neccesary) manual stuff and analysis.

I have to adapt spamassassin rules daily and curently there are  arround
11 million spams trashed per day
