Hello, I am trying to set up my postfix server so that it sends outgoing emails having a from address matching *@pobox.com to the server smtp.pobox.com, using port 587. As this rule is matching from addresses, and pobox.com is not the final destination, smtp.pobox.com requires authentication.
I saw several references on the web explaining how to do this, such as: https://swientek.me/2013/11/27/postfix-smtp-sender-dependent-authentication/ I did what it said, and I seem to have gotten the server to correctly recognize which emails need to be routed to pobox.com, and I'm able to get server to connect to smtp.pobox.com. But when my server connects it refuses to authenticate, so smtp.pobox.com responds with "Relay access denied". (Note debug_peer_list = pobox.com below.) Other (non pobox.com) email is working fine in both directions. I've tried a bunch of things, but now I am stumped. If anyone has any thoughts on what to try and/or if they need more information, please let me know. Thanks! -Bob Relevant files: /etc/postfix/sender_relay @pobox.com [smtp.pobox.com]:587 /etc/postfix/sasl_passwd [smtp.pobox.com] <UserID>:<Password> [smtp.pobox.com]:587 <UserID>:<Password> @pobox.com <UserID>:<Password> *I believe only the first entry is needed,but I added the others to see if I could get authentication working.
