see if following helps you, also for filtering a domain/recipient you can
use black hole in alias
##
if $message_body matches "name=\"{0,1}readme\\\\.eml"
then
  if $message_body CONTAINS "====_ABC1234567890DEF===="
  then
    fail text "This message has been rejected because it has the
signature\n\
              of the W32.Nimda.A viru/worm in it"
    seen finish
endif
endif
