Multiple Domains on Exchange - Non default email address

Hi Guys, hopefully a simple question for you!
I am setting up our exchange server to accept emails from a second domain, so I have gone to the recipients policy in exchange manager and added the new domain there, so far so good!
However, as only a very few people in our organisation are going to use this domain, I have taken the tick out of the tick box agains tthe new doamin with a view to manualy adding the email addresses to the users inactive directory that require it.

My question is:  Now that I have un-ticked the new domain in the recipient policy, will it prevent emails from that domain behind accepted by exchange, or does it just stop the email addresses being automatically created for new users in the AD?

Hi Claimar,

No, it won't prevent mails to be received for that domain, it just won't be added as address to new users that's created. If you are unsure, you can:

Right click on the new domain policy
Click on properties
Click on email addresses (Policy)
Click on SMTP and click on Edit
Make sure "This Exchange Organization is responsible for all mail delivery to this address" is ticked.
