I have a backend exchange server and two front-end exchange servers. All
are running Exchange 2003 Enterprise with SP1. The backend is called "BE1",
and the frontend servers are "FE1" and "FE2".

I would like to setup FE1 to recieve all inbound email from the internet,
and FE2 to send all outbound email to the internet. How do I configure the
SMTP virtual servers and the SMTP connectors on all three servers? Should
the Virtual servers ONLY be running on the frontend servers?

Thank you in advance.

Hi,

To answer your questions.. assuming there is nothing configured right now.

For incoming mail ..

Configure your MX record to point to FE1. When it receives the mail it
will do a directory look up against Active Directory, and work out that the
mailbox resides on your back end server, and forward it.

For Outbound mail.

Create an SMTP Connector with the address space of *. Set the bridgehead
of that to be FE2. When the back end server has mail to send, it will pass
it to FE 2, which will forward it to the internet.

That's all that is needed.

Kind regards,
Rob Wilcox

Thanks Rob.

Here's what I've done.

I added an SMTP connector with * address space, and selected the smtp VS on
FE2. I think this is what you are saying to do. For some reason, that
"broke" the external mail flow - in other words outbound messages starting
building in the "messages waiting to be routed" queue.

Should I consider creating an smtp connector BE1 to add FE2 as a smarthost?
Then, I could let the smtp VS on FE1 handle the outbound mailflow?

Thank you for your time.

Tim

The two FE servers will be used to control mailflow and enhance security;
one for inbound and one for outbound.
