I noticed I was running postfix 3.1.0. Freebsd has rev 3.1.1, so I figured I would upgrade.
Fist up, I reviewed the page I used as a starting point for setting up my mail server, namely http://blog.iandreev.com/?p=1604 In the configuration for postfix, the SPF option is not selected. Somewhere in my journey of setting up postfix, I ended up adding this to the master.cf: -------------------------------- policyd-spf unix - n n - 0 spawn user=nobody argv=/usr/local/bin/policyd-spf -------------------------------- My main.cf has this relative to spf: ------------------------------------- smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination, check_client_access hash:/usr/local/etc/postfix/rbl_override, reject_rbl_client zen.spamhaus.org, reject_rbl_client bl.spamcop.net, reject_rbl_client cbl.abuseat.org, reject_rbl_client b.barracudacentral.org, reject_rbl_client ix.dnsbl.manitu.net, reject_rbl_client rabl.nuclearelephant.com, check_policy_service unix:private/policyd-spf, permit smtpd_relay_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination policyd-spf_time_limit = 3600 #policy_time_limit = 3600 mailbox_size_limit = 0 message_size_limit = 0 virtual_mailbox_limit = 0 ------------------------------------------------------- As far as I can tell, I pass the SPF tests based on the various email certification services. So should I select the spf option when I upgrade? I'm hesitant to break what doesn't need fixing.
