Under these conditions messages will contain a few headers which it may be worthwhile to scan, e.g.: From: has the sender been forged? To: are there addresses which mail should not be sent to? Subject: should a subject line always be present? Date: is it within, say, 5 minutes of the server's time?
If your users can send messages via other routes forget it. Its not possible to scan messages that are sent directly to external MTAs. Since you haven't described your mail set-up its not possible to say more than this. Martin
