I need to be able to force secure TLS mail coming from my end to a specific third party both ways. In my main.cf I have the line smtp_tls_policy_maps=hash:/etc/postfix/tls_per_site. This file contains the IPAaddresses of the mail servers with the none command level. My questions is can I put the third party domain names which need to go force TLS both ways in this file or should I map smtp_tls_policy_maps = hash:/etc/postfix/tls_policy then create this file TLS_policy and put them in that file. Thanks Viv
