Note that +Mail::SPF is a complete re-implementation of SPF based on the final SPF RFC, +RFC 4408. It shares no code with the older Mail::SPF::Query that was the +original SPF development implementation. + +This version of the policy server will reject mail that fails either Mail From +or HELO SPF checks. It always checks HELO (older versions just checked HELO if +Mail From was null). It will defer mail if there is a temporary SPF error and +the message would othersise be permitted (DEFER_IF_PERMIT). Otherwise, it will +PREPEND the appropriate SPF Received header. In the case of multi-recipient +mail, multiple headers will get appended. Error conditions within the policy +server (that don't result in a crash) or from Mail::SPF will return DUNNO. + +.SH "DESCRIPTION" +.IX Header "DESCRIPTION" + +Logging is sent to syslogd. + +Each time a Postfix SMTP server process is started it connects to the policy +service socket and Postfix runs one instance of this Perls script. By +default, a Postfix SMTP server process terminates after 100 seconds of idle +time, or after serving 100 clients. Thus, the cost of starting this Perl +script is smoothed over time + +The default policy_time_limit is 1000 seconds. This may be too short for some +SMTP transactions to complete. As recommended in SMTPD_POLICY_README, this +should be extended to 3600 seconds. To do so, set "policy_time_limit = 3600" +in /etc/postfix/main.cf. + +.SH "TESTING THE POLICY DAEMON" +.IX Header "TESTING THE POLICY DAEMON" +Testing the policy daemon + +To test the policy daemon by hand, execute: + + % perl /usr/sbin/postfix-policyd-spf-perl + +Each query is a bunch of attributes.
