# Melissa:
# only works if Melissa is predictible and conformist...
#
if $header_Subject contains "Important Message From" and
   $message_body contains
    "Here is that document you asked for... don't show anyone else" then
  testprint "Melissa header and body part seen from $sender_address"
  freeze text
   "Melissa header and body part  seen. \n \
    Message may contain Melissa Word Macro Virus\n $message_headers"
endif
#



It would be nice to be able to freeze the message *and* generate an
autoreply to the sender to let them know the bad news. Any ideas?

We've caught a fair number of HAPPY99.EXEs like this as well

I can see this becoming an unpleasantly regular thing and
increased justification for running virus scanning at delivery.
