I can think of some very good reasons to run a second instance of SMTP, for instance,
providing roaming mail service to a large userbase who dialup through earthlink.
Earthlink blocks any other SMTP than their own when their users dial up, so with a
second SMTP server on another port, you effectively can bypass that problem.
I run my SMTP through supervise, so all I had to do was go into
/var/qmail/supervise/qmail-smtpd, and edit the run script. In the run script, just
copy your whole command
line in after the first instance, and change the port. Restart your mail, and you're
all set (if you want to use a named port, you have to add the name in /etc/services,
otherwise you'll use a number).
Nothing to it.
