SMTP SmartHost authentication problem

NethServer Version: NethServer release 7.3.1611
Module: i don’t know
Good morning
i have a account for smtp autenitcate but nbot function
the port is 465
the user is example and the psw is example Ap.456,smtp

Do you see any error in /var/log/maillog ?

92055454597:,[]:465, delay=780, delays=479/0.04/300/0, dsn=4.4.2, status=deferred (conversation with[] timed out while receiving the initial server greeting)

the relay ip and name is occasional

IIRC port 465 (SMTP over SSL) does not work with Postfix on NethServer.

Only submission (port 587) with STARTTLS can work.

I think it should be documented here

…we should improve our docs /cc @docs_team

Only solution for smarthost is user and psw and port 25
the user and psw on port 465 and SSL not function
the user and psw on port 587 and STARTTLS not function
Is it correct?

It depends on your SMTP provider!

Does it allow SMTP AUTH on port 25 after STARTTLS?

my provider support 465 SSL

The official Postfix documentation explains how to configure it

…it seems your provider uses a deprecated TCP port!

thank you very very mutch
