2 Domain Names 1 Exchange 2003 Server 5

[JRosario78]

Hi,

I would like to know what would be needed to have 2 domain names on 1 exchange server.

We have users using company.com as the default email. We would like to add company.org as well but to be the default email address and the company.com as secondary.

We created the company.org SMTP within the users template in the Exchange Management Console and all users show up with it. We then set the company.org SMTP as the default. The users are able to send emails as user@company.org. When trying to reply to an email sent from company.org, we receive a bounce back.

I would like to know if the below is what is need to make this work?

1. Go to Go Daddy and point the MX record to our external IP.
2. Have our ISP create a reverse DNS for our external IP.

Thanks in advance…

Modify your recipient policy to add the new domain. It will add that new domain email address to all your mailboxes for you.

You also need to do your 1 & 2 if you haven't done so already

1. Go to Go Daddy and point the MX record to our external IP.
2. Have our ISP create a reverse DNS for our external IP.

Actually, for step 1, you want to go to Go Daddy and create a host record for mail.company.org pointing to your external IP. Then point the MX record to mail.company.org. MX records are not supposed to point to an IP, they should point to a DNS name.

For step 2, it wouldn't necessarily be your ISP, that might be done at Go Daddy as well. It needs to be done where ever your DNS is hosted.

Actually both steps should be done at the same place as they are both DNS issues.

Reverse DNS MUST be done at whoever owns the public IP address. That's always the ISP.

Didn't know that. They've always been the same for me so I just <mistakenly> thought they were done at the same place.

You can also use Microsoft's ADModify (ftp://ftp.microsoft.com/PSS/Tools/Exchange%20Support%20Tools/ADModify/) to add the new domain to all you existing email accounts by container rather than one at a time.

Recipient Policies are designed for this, and the recommended method. If a domain doesn't appear in a recipient policy, the server won't accept mail for it. You don't have to touch ANY accounts (generally)
