What I do is block at the SMTP connection level any mail with an SMTP from address of @yahoo.com @aol.com @msn.com or @hotmail.com and the sending server does not have a corresponding DNS entry for that domain (hotmail and msn are allowed from each other, too). This blocks an ungodly number of spams, and only rejects ligitimate mail when one of your users uses a forwarding service that has friends who send from the free mail services. _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm _______________________________________________ Spamassassin-talk mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/spamassassin-talk
