For various reasons it has been decided that internal users will only be
allowed to use IMAPS/Submiission for email.
Our setup is a fairly conventional Postfix/Dovecot/Amavis/... on
Debian/Ubuntu.
q1) am i correct in assuming that the smtpd section of main.cf is aimed
at SMTP (tcp port 25)
and the the "submission" section in master.cf is aimed at TCP
port 587.
q2) is it possible (or desirable) to deign staff the ability to send via
port 25, while allowing the rest of the world to send to port 25.
and the obverse is it possible to allow only staff access to
port 587.
I remember seeing an article that proposed such a setup, however Google
has not been my friend this time.
I have not included either postconf -n or master, but I can if they
would help.
Help would be appreciated.
