Ah -- actually there is a crucial difference in the way SpamAssassin and milter-spf work. SpamAssassin uses the SPF status of a message to add to the spam score it calculates -- typically, a message which passes all the SPF checks has an approximately zero result on Spam scoring, as will a message where there is no SPF stuff available at all; but one which fails the SPF tests will get about 3 spam points. (Which means that even a message failing SPF checks can be passed as ham) milter-spf however operates in a binary fashion -- anything that fails is rejected, anything that passes is accepted. In general I prefer the SpamAssassin behaviour -- not all the world has immediately accepted SPF as a good tool against spam; there are any number of edge cases where a legitimate message can contradict what the SPF settings say (mail forwarding is a particular problem) and one of the groups that has adopted SPF most wholeheartedly are in fact, the Spammers themselves. SpamAssassin processing is however much heavier on system resources than milter-spf.

Check the setting in MailScanner.conf located in: /usr/local/etc/MailScanner -Derek Sendmail has milter built-in to it for some time. All the mail scanning tools need milter. The easy way to configure these tools is to configure MailScanner. It sits at the top of the tree so to speak, depending on whatever AV you configure it to use, and MailScanner uses spamassasin and many perl libraries. You can see all the dependencies if you do: make depends on the mailscanner port. You will need to configure your AV to get updates. Also you may want to setup some of the rules files for mailscanner for whitelisting, blacklisting, and phishing. One last note, don't bounce spam. If you choose to bounce spam, as most has wrong return addresses you can start your own mail storm of rejected bounces. A mail storm like that will easily bring down an email server. -Derek -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
