Hi,

I've learned that port 465 is reserved/utilized for secure SMTP. Does this
also apply to ESMTP? I'm guessing so.

>From FreeBSD's /etc/services
smtp             25/tcp    mail         #Simple Mail Transfer
smtp             25/udp    mail         #Simple Mail Transfer
smtps           465/tcp    #smtp protocol over TLS/SSL (was ssmtp)
smtps           465/udp    #smtp protocol over TLS/SSL (was ssmtp)

Since Courier supports secure POP3 and secure IMAP with simple config file
changes would it be possible to add in the support for secure &
authenticated RELAYING to the install? (Assuming it's not in there already
somehow). Actually the first step is setting it up on my current system.

Ok, so I can run a "courieresmtpd" on port 465 that is configured for ssl
and authentication access only. What would the configuration file for this
"second" instance of courieresmtpd look like? Wouldn't I have to be carefull
to chop out stuff related to other things so that I don't make a mess? Or
would it simply be a copy of the config file(s)? (Which config files?) Your
wisdom is appreciated.

All the best,

Peter - novice courier admin learning quickly
