SPF running in conjunction with Postfix will only do verification. http://www.openspf.org/Software lists the packages known to work properly. What makes you think you have a problem? That said, make sure to police your users effectively. Use antivirus and antispam (do install spamassassin). Read through http://www.openspf.org/ for issues on SPF. REQUIRE SASL for users on untrusted networks. If you want further help with a specific case, post (non-verbose) logs of a transaction and 'postconf -n'. Brian
