How do I route email from 2 MX records? 3

[dico]

Hi Guys,

My Company is about to change it's name hence we have registered a new Domain an expect mail from this new doamin name. We still want to receive mail sent to the old Domain name.
If both MX records are pointed at the mail server how do I configure Exchange so users can pick mail from the old and new domains?
Tough one!

you'll have to add the new domain name on your Routing tab in the IMC as <inbound>. Then, on your mailboxes, you can have both email domain suffixes for each user (or just one), or create new accounts for the new domain suffix.

I am assuming you are using Exchange 5.5. Just go to your Exchange administrator, Connections, Internet mail service.
Open it up and click on the Routing Tab.

Tick the button (if it is not already ticked &quot;Reroute incoming SMTP mail&quot;

Add an entry for each domain for which you want to receive internet mail. Route it to &quot;incoming&quot;

e.g. sent to: domainx.com Route to: incoming
sent to: domainy.com Route to: incoming

Of course, this is assuming that you already have the MX records in your external DNS for both domains already pointed to your exchange server.

hope this helps,
Dana

I think a better way IMO would be to set your users up with their e-mail address @newdomain.com and set the IMS to route newdomain.com as <inbound>, and route olddomain.com to newdomain.com

So if you have a user with an e-mail address of John@newdomain.com, then mail arriving for John@newdomain.com or John@olddomain.com will still be sent to the same mailbox.

This way, you don't have to maintain e-mail address for both domains. And the sending/replyto e-mail address that every user's outgoing e-mail will be stamped with will be @newdomain.com

The re-routing doesn't send the e-mail back out into the internet - it all happens internally on the exchange server.
