Second Domain not Receiving external email 1

[Sweetworks]

I regeistered a new domain for the sole purpose of receiving e-mail with a different domain on our exchange server.

I had the organization that hosts my DNS records create an MX record that points to the external address of my firewall. My firewall translates any SMTP traffic that hits it to go to the internal address of my exchange server.
My firewall doesn't care what the Destination Address is, it just forwards all traffic on Port 25 to the internal address.
I've done an nslookup of both domains and they both state the external address of my firwall.

In AD I added an SMTP address to my account called "MYNAME@NEWDOMAIN.COM", so exchange should know the address. (I can send out with that domain, heck I can send out with any domain name.)

When I send a message from my yahoo account I receive the following error.
________________________________________________________
Message from yahoo.com.
Unable to deliver message to the following address(es).

<MYNAME@NEWDOMAIN.COM>:
XXX.XXX.XXX.XXX does not like recipient.
Remote host said: 550 5.7.1 Unable to relay for MYNAME@NEWDOMAIN.COM
Giving up on XXX.XXX.XXX.XXX.
_______________________________________________________

The IP address is correctly stated as my Firewalls IP address.

What am I missing?
Do I need to add an SMTP connector in the Exchange System Manager? If so where?

Thanks

You must add a second mx record in your local dns for this new domain name.

OK. I went to my internal DNS server.

I created a Zone called &quot;NEWDOMAIN.COM&quot;
I created an MX record called Mail, that points to my Exchange servers IP Address.

I sent a test message and it bounced back.

You also need to set the domain in your Recipient Policies in Exchange System Manager, so that Exchange knows it should handle e-mail for this additional domain.

In ESM go to Recipients, Recipient Policies. Go to the properties for the Default Policy (if that is the only one), or your highest priority policy. [ul][li]Click on the E-mail Addresses (Policy) tab[/li] [li]Click on the New button[/li] [li]Select SMTP Address and click OK[/li] [li]Enter the address as @domain.com, and be sure the checkbox to make Exchange responsible for delivery is checked[/li] [li]Click OK[/li] [li]Click OK[/li][/ul]
It may ask if you want to update all recipients. If you do, it will automatically create a second address for them with the new domain. If you don't, you can add the second address manually.

If your DNS records really are correct then this should fix it.

Great... That worked

I have the same problem but with Exchange 5.5, does anyone know what I need to do? I am also a novice on DNS and not sure if we run an internal one.

Thanks

I have multiple domains.
These are multiple virtual servers under one organizational unit in Exchange 2000.
In the SMTP VS, when I set Relay to Allow only the list below and try to send from outside (like yahoo) I get this:

XXX.XXX.XXX.XXX does not like recipient.
Remote host said: 550 5.7.1 Unable to relay for
<user....>

so it mean it was bounced back by my exchange server XXX.XXX.XXX.XXX .

I have tried Microsoft Knowledge Base Article - 323669
deleting LM/DS2BM with MetaEdit. It comes does no good and comes back.

I have tried Microsoft Knowledge Base Article - 289553
which is ad a Recipient policy.

the problem is the outside email only reach to the primary email address not other domain names.

Also, under relaying, allowing my subnet to relay doesn't seem to help. I thought it did but it doesn't seem to make a difference now.

Please Help. I'm dying here.
Thank for any advice !!!!!!!!!!!!
