DNS chnage for our own exchange server

We use cp.xo.com's e-mail service but we are trying to have our own mail server
Let's say the domain name is "aaa.com" (for example)

Now
1. e-mail service - cp.xo.com
2. Domain name registry - networksolution.com
3. DNS - networksoultion.com points cp.xo.com's DNS
4. ISP - sprint

1st Plan
1. e-mail service - our comany's own exchange server (mail.aaa.com)
2. Domain name registry - networksolution.com
3. DNS - networksoultion.com points sprint's DNS
4. ISP - sprint
5. Register our exchange server name and IP Address( A & MX record ) to sprint's DNS

2nd Plan
1. e-mail service - our comany's own exchange server (mail.aaa.com)
2. Domain name registry - networksolution.com
3. DNS - networksoultion.com points networksolution's DNS
4. ISP - sprint
5. Register our exchange server name and IP Address( A & MX record ) to networksolution's DNS


My original plan was 1st plan thru Friday night to Sunday because I have to get it done by Sunday night to use e-mail service from next Monday with our exchange server. But somethings happened with sprint which is our ISP. They say they won't update DNS on weekend which I didn't know.

So I change my plan as 2nd plan to use DNS of networksolution.com

Do you think the 2nd plan is going to make our own mail server work without register our exchange server information(domain name and IP address) with sprint (our T1 line internet service provider)?

Hi Man rippo,

Might need a bit more info here, but from what I can make out you use a 3rd party supplier for your email.  So, perhaps you have your Outlook clients pointing to their serve for email?

In this case I would do this (sounds like your plan 2).

1) Register your new domain name via Sprint if possible, or via networksolutions.

2) Register the MX record for your new domain to point at your mail server IP address, you do not need to register the name.

3)  Add your new domain name to the recipient policy on your exchange server

You should then be up and running.

Can you explain little bit more about "recipient policy"  for how to add?

Yes, if you go into Exchange System Manager you will see a section called recipient policy.  Go into the default recipient policy and add your domain - i.e manrippo.com into the list.

This will make the server accept mail for that domain.
