Hello, TL;DR: I need to setup different configuration for two different relays... and I can't see if this is possible and how to do it.
I have a Postfix problem and very limited internet access (I've just subscribed to the mailing list but I'm not sure if I'll be able to download all the messages, feel free to CC me) (I'm on an the ACE Antarctic expedition right now helping with software/networking/data management/setting up equipment). The problem is that I setup a Postfix server that is used just to relay to different SMTP servers (so users don't need to be waiting for the internet connection on their Thunderbird/others). The setup is not ideal and it's only for 3 users that use different email addresses (yahoo.co.uk and two different institutional domains). For the relay authentication and setup: My sasl_passwd file that looks like: [RELAY_IP1]:465 user1:password1 [RELAY_IP2]:587 user2:psasword2 And I have a relayhost_map: user1 [RELAY_IP1]:465 user2 [RELAY_IP2]:587 Users connect to the Postfix using Thunderbird, authenticated SMTP. The problem is that user1's SMTP server needs these settings: smtp_tls_wrappermode = yes smtp_tls_security_level = encrypt and user2's SMTP server: smtp_tls_wrappermode = yes smtp_tls_security_level = may Here the question: I've been playing with the transport table to do something like (I've found it on the internet): [RELAY_IP1]:465 relay-smtps[RELAY_IP1]:465 And then in the master.cf table: relay-smtps unix - - y - - smtp # This server default is SMTPS unless goes to relay-nosmtps -o smtp_tls_security_level=encrypt -o smtp_tls_wrappermode=yes But my understanding at the moment is that the transport table only affects depending on the recipient of the email, not on the next relay host. Is it possible to do what I want to do? How? Because at the moment it seems impossible to me :-( Thank you very much!
