I know Ex5.5 is different from E2k, but SMTP is SMTP is SMTP...regardless of
flavor.
We have a mail relayer set up in our DMZ, with the MX record pointing to
that one server...like you do for www.misd.net.
misd.net MX preference = 10, mail exchanger = apollo.misd.net
apollo.misd.net internet address = 64.88.0.98
We have the mail relayer set to only accept e-mail for valid e-mail accounts
in our domain. The firewall is configured to only allow port 25 traffic
from the MR to the Exchange IMS. At that point, the IMS sends to the
mailboxes. All outbound e-mail goes out through the proxy server ->
firewall -> Internet.

Subject: Inbound/Outbound Mail Question
I have an Imail server on the outside of my firewall (PIX) and an Exchange
2000 server on the inside. I use an Imail server as a gateway virus/spam
scanner. All mail comes through my Imail server where it is scanned for
viruses and spam. From the Imail server, all mail is forwarded to mailboxes
on Exchange. It works really good except that I am still receiving messages
directly to the Exchange server mailbox, bypassing Imail.
Basically, I want to only accept mail that comes from the Imail server.
Should this be forced from the firewall or from Exchange? If I set inbound
connections to only come from Imail what does that do to outgoing mail?
What do I need to do to insure outbound delivery from Exchange...not out
through Imail.
In through Imail...through firewall.....to Exchange....Out through
Firwall???
