And please see the following defaults, root@mail:~# postconf -d smtp_use_tls smtp_use_tls = no root@mail:~# postconf -d smtp_tls_security_level smtp_tls_security_level =
under these defaults, I am afraid if I don't setup them, postfix will always talk to peer with plaintext, even peer supports starttls. Am I right?
I ask this is b/c when i just run 'apt install postfix' to make postfix as a relay for my another server (with most defaults setup). since I changed nothing on smtp_tls_* stuff, it always talk to peers with plaintext, and peer may reject this talk session (such as gmail server?).
Thank you again. regards. _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
