Where can I find my SMTP username and password?

Question

linux

Hello! Where can I find the password and login for the SMTP server?
There is a bunch of Postfix + Dovecot
OS: Debian 8.5 Jessie

Answer 1

And why do you think that your SMTP has a separate login-password? Classic - user login-password is used. There are certainly options with "external" authorization.

Answer 2

Most often, there is no login and password for SMTP.
If SASL authentication is enabled in popstfix, then look in main.cf for the smtpd_sasl_* parameters, they describe the type and parameters of authentication.

Answer 3

Why look for him? Is SASL worth it? Then this is the login and password of local users (or domain - depending on NSS). If there is no SASL, then the SMTP login and password are not needed.
