Hi,

Firstly I'd like to thank those that helped and after
a few suggestions perhaps I should make myself clearer
as to what I want to do and to see if it can be
achieved.

I deal with the computers at a local K-12 school, I
will be first to admit that I know very little with
regard to email.

At present anyone that wants an e-mail address asks me
for an email address and I create them one using
postfix, it works I don't need to tweak it, I just
leave it alone.

With the need for email developing I would like to
give the older children email accounts.

I use windows 2003 server active directory for the
accounts so I thought I would put exchange on a
machine, that would then create the email users for
me, it would give me the option to use the out of the
box configured OWA - Outlook Web Access etc.

In short what I would like to use postfix as what I
understand to be a mailrelay. That is I would like to
use the postfix machine to sit in the DMZ and receive
mail for the users already with exchange accounts. Can
I have it that the mail sits on the postfix machine
until the exchange mail pulls it down?

At present I have a user called testmydomain.com, I
can send an email to him and the email sits on the
postfix machine. How can I have it that the user test
on the exchange pulls that message down from postfix?
Is that possible? Is there a how-to? I do not want to
open up pin holes in my DMZ for this to happen? Is
there a better way of doing this?

Thanks,

Andrew
