All-

Anyone ever worked with multiple SMTP virtual servers on the same Exchange
box?

We have a small shop with a single Exchange 2003 server. Naturally, I have
to allow unauthenticated/unencrypted TCP-25 traffic to flow to the box to
accept new mail from the Internet. Our remote users pickup e-mail via IMAP
over SSL (TCP-993) but just use the same SMTP port (25) to drop off their
outbound e-mail.

Ideally, I would like to setup a 2nd SMTP virtual server on ... say ... port
2525 that works over SSL and only allows authenticated users to interact
with it. I am hoping there is then a way to configure outbound messages send
to *this* port to be forwarded to the original SMTP virtual server on port
25, and then out to the Internet.

The idea is: internal users would be able to communicate with internal users
over encrypted channels for both sending and receiving messages. Obviously,
there is not much I can do once a message leaves our network and hits the
Internet.

Anyway, is this possible?
