One of SpamAssassins weaknesses is that it only has access to the message body of the email. It can't create rules to detect certain behaviours of the connecting host during delivery.



MAIL FROM:<u...@example.com> SIZE=12345

that would trash everyone running cisco firewalls with smtp fixup (or as we call it here, smtp screwup)
