My first question is why? Is there any GOOD reason why your users
can't just use Earthlink's own SMTP server? That's the way it's meant
to work. The only good reason I know of to not use the server your
ISP intends you to use is if they stop you using non-provider From:
headers. Earthlink doesn't do that.
Well, OK, two other reasons (good or otherwise) that I hear are,
firstly, so that all dialup users' configurations can be set up the
same, and secondly, to make support easier (so you don't get blamed
for the ISP's problems).
If you HAVE to do it, then there should be no reason why you can't run
tcpserver/qmail-smtpd from several different ports. After all, a new
qmail-smtpd is invoked for each connection, so it already handles
concurrency.
I hope for your sake that you are using a GOOD method of ensuring your
email servers are not open relays.
