Getting #550 5.1.1 RESOLVER.ADR.RecipNotFound; not found ## in exchange 2010

I just added a second domain to my exchange 2010 server using these instructions 

I used the powershell version.

Now the new domain is considered the primary domain.

I tested everything with and all of the DNS stuff basically correct.   I am getting

Warning - Reverse DNS does not match SMTP Banner
Warning - Does not support TLS.

The first one requires a reverse mx record created by my ISP, not sure how to fix the TLS support issue..But more importantly, when i send a mail to the primary domain, i get this response back

#550 5.1.1 RESOLVER.ADR.RecipNotFound; not found ##

When i send an email to the secondary domain, they don't get rejected.

When i view the messages in OWA, the TO: shows it was sent to the primary domain even thought the messages was actually sent to the secondary domain.

Any thoughts???

What version of exchange is the old server running? For Exchange 2010 in EMC go to Organization configuration/hub transport/accepted domain and remove the old domain.


First you will need to make sure the domain is not in use by any e-mail address policy.

Here is the MS technet  on it.
You require to change the user primary email address to the new domain.
and to make change for all users. make the change in the reciepent update policy to change the new email address as primary address

Thats already set correctly.. When i goto

Recipient configuration > mailbox > Pick the user > properties > E-mail addresses

I see the new primary domain in bold...

Figured it out.. My bad..   But still need some help.  

The server that i was using to send the test messages was at one time the system where the primary domain was hosted.. So i cut over the mx records but forgot to remove it from this other exchange server..

So, my new question is: how do i remove this secondary domain from my other email server????
