I apologize if this does show up on the list as a duplicate (it is not in the archive (yet)). I wasn't a member of the list when I sent it (I was rejoining).
-------- Original Message -------- Subject: restrict submission Date: Fri, 17 Aug 2012 01:05:24 -0400 From: James <bjloc...@lockie.ca> To: Postfix users Mailing List <postfix-users@postfix.org> Here's what I did and what I want. I run my own postfix server for my domain. I receive mail for my local users and I assume that is port 25. I currently allow only the local domain to submit mail (if on another network I use ssl port forwarding of port 25). I would like for any authenticated user (from any network) to be able to submit mail. I was thinking of doing it with TLS but if I require TLS, will the server still receive mail? I started to setup TLS but Thunderbird alwways timed out and /var/log/mail didn't say anything. This what I started with in /etc/postfix/main.cf smtpd_tls_loglevel = 3 smtpd_tls_cert_file=/backup/certs/mailcert.pem smtpd_tls_key_file=/backup/certs/mailkey.pem smtpd_tls_security_level = encrypt smtpd_tls_req_ccert = yes smtpd_tls_session_cache_database = btree:/var/lib/postfix/smtpd_scache smtpd_tls_always_issue_session_ids = no permit_tls_all_clientcerts = yes # this isn't even a command but was in the documentation
