in master.cf file by default only the normal smtp service is enabled.
You can enable submission on port 587
Sometimes people enable smtps service (port 465), for some compatibility
with some older clients (outlook express etc) although most new clients
you can define the port.
my config looks like this:
smtps inet n - n - - smtpd -o smtpd_tls_wrappermode=yes -o
smtpd_sasl_auth_enable=yes
587 inet n - n - - smtpd -o smtpd_enforce_tls=yes -o
smtpd_sasl_auth_enable=yes
you are probably better just using port 587 (submission) for auth as
it's a common thing to expect.
for example, master.cf comes pre-setup for enabling smtp auth on the
submission port.

Hello
we have a in house mail system based on postfix.
We would like to optionnaly integrate AUTH for SMTP
I wonder if it would be possible to
have SMTP/postfix listen on port 25 and say port 26
with the following setttings
* port 25 does not require AUTH
* port 26 requires AUTH
( we would be restricting access to port 25 to given subnets )
Is it possible ?
Sincerely,
Fred
