[SOLVED] Doubt about Postfix and smtp / submission

circus78 · 02-09-2018, 07:12 AM

Hi,
let's say I configured some parameters on main.cf file:

Code:

smtp_use_tls = yes
smtp_tls_security_level = may
smtp_sasl_path = /var/run/saslauthd/mux
smtp_sasl_mechanism_filter = plain, login

and so on..

Now, I would like to provide some functionalities on 587/TCP port.
Should I use master.cf (the line which starts with "submission" string) and repeat same options? I mean:

Code:

submission inet n      -       n       -       -       smtpd
        -o smtp_use_tls = yes
        -o smtp_tls_security_level = may
        -o smtp_sasl_path = /var/run/saslauthd/mux
..

or is there a better way?
Thank you very much

According to master.cf man page:

http://www.postfix.org/master.5.html

Code:

-o name=value (short form)
                     Override the named main.cf configuration  parameter.  The
                     parameter  value  can  refer to other parameters as $name
                     etc., just like in main.cf.  See postconf(5) for  syntax.

Only overrides are evaluated in master.cf

So, if I want same options on 25/TCP and 587/TCP port, I don't need to config anything in master.cf (I need to comment out "submission" line, of course).
