One of our overseas agencies wants us to set up SMTP access on a
port other than port 25.
Is this possible in Perdition? If so how is it done?
Regards
Paul

Blink? Come again?
Perdition is a POP3/IMAP proxy, SMTP never enters its picture. ^o^
Pretty much all MTAs I'm aware of can listen on ports other than 25 and
of course you could do port forwarding in a number of ways, depending on
your OS platform.

Hi Paul,
perdition doesn't handle SMTP, so its not the tool that you want for this job.
Without understanding what it is you want to do I would suggest
that the easiest way would be to reconfigure your SMTP daemon
to listen on the extra ports directly.

Perdition is a proxy for POP and IMAP, not SMTP. May you want to look at
using the email submission port 587?

It's absolutely normal, and even recommended, to set up SMTP access for
clients on port 587 provided that you must require authentication for
connections on that port. It's quite likely that your SMTP server supports
authenticated connections on port 587.
The service (SMTP on port 587) is called Message Submission Agent, and is
required to bypass the blocks that many ISPs put on direct connections on
port 25.

Paul

If I had my way here at UC Davis, our mail servers would be thus:
smtp.ucdavis.edu: port 587 (only)
mx.ucdavis.edu: port 25 (only)
Alas, the legacy of previous decade practice means I have to
allow port 25 on my SMTP pool systems. For on-campus
we allow relaying on that port, for off-campus you must
authenticate.
