Hello everybody, i have a postfix server. Amavis & postgrey plugins are already installed on it and work perfectly. I would like to configure spf plugin. I installed the package and adjusted the config. I added a new record in /etc/postfix/master.cf. : policyd-spf unix - n n - 0 spawn user=policyd-spf argv=/usr/libexec/postfix/policyd-spf and in /etc/postfix/main.cf : smtpd_recipient_restrictions = check_policy_service unix:/var/spool/postfix/policyd-spf, permit policy_time_limit = 3600 Ps: i have add a new user " policy-spf" manually. and the I restarted the postfix. In / var / log / maillog I don't have any logs related to spf. I'm not sure if the child process was triggered in master.cf. Can anyone help me? It would be great if the config is explained step by step. have I configured something wrong? still missing a step? Many Thanks!
