Setting up Exchange to receive external mail 1

[DanMIS]

Currently we have a Linux server that receives inbound mail from the internet, and our clients (Outlook) use POP3 to deliver that mail into their Exchange mailboxes.

We want to get rid of the extra step, and have the inbound mail deliver directly into Exchange.

Is it as simple as updating the MX record of our domain in DNS?

Your MX record has to be know 'worldwide', not just your DNS.
Port 25 needs to be open and pointing to the targetted server's IP address, directly or via port-forwarding on a router/firewall.

Depending on your server setup, you could also have the Linux box receive the e-mails and then forward them on to the Exchange box. I did this at church to perform anti-virus/anti-spam scans on the e-mails before they got to the Exchange box and thus the users' mailboxes.

Thanks for the help so far. We're in the process of moving mail off the Linux box, then we'll go with a front/back end server configuration. We'll probably go with having the front-end server do SPAM and virus filtering, and back-end server run anti-virus.

First we have to digest the many different configuration possibilities with firewalls, ISA etc. There's a lot of options!

What crobin says makes sense of course.
Have a look at ASTARO, a very neat solution!
