That's acceptable damage. We have manual whitelisting and automatic whitelisting in place to mitigate this. Also, under the example you've provided, I'd only be adding SpamAssassin points, not blocking outright. This helps limit the problem, especially since users set their own spam filtering level. I've only heard of a couple cases where messages are eventually being rejected by SpamAssassin because of the 5 points I add for failing this test. After contacting the administrators, this usually gets fixed immediately. > MS outlook express PCs often send their NETBIOS names as the HELO I don't perform these checks for local machines or clients who have SMTP authenticated. MUAs do a lot of stupid things, so I have a lot of exceptions for local users. -- Richard Laager <[EMAIL PROTECTED]> Wikstrom Telecom Internet _______________________________________________ Visit http://www.mimedefang.org and http://www.canit.ca MIMEDefang mailing list [email protected] http://lists.roaringpenguin.com/mailman/listinfo/mimedefang
