There is no IP-based analogon for smtpd_sender_login_mapss, due to lack of demand. If you don't have a huge number of such IP addresses, perhaps a plugin with https://www.postfwd.org/ can do this. main.cf: smtpd_sender_restrictions = check_policy_service inet:127.0.0.1:12345 Make sure that this will not affect the services for submission (port 587) and submissions (port 465) in master.cf. They should look like: master.cf: submission inet n - n - - smtpd ... -o smtpd_sender_restrictions= ... submissions inet n - n - - smtpd ... -o smtpd_sender_restrictions= ... Alternatively, milter-regex may be able to do this.
