In the zone, you should to create a host record to let DNS know that there is a machine with the
name of your SharePoint server using the domain alias. It is not strictly necessary; you can simply
add the MX without it, but it is considered bad form. Then using that A record, you can create an
MX record to let DNS know that the new host is a mail server. To do that, follow these steps:
To add a host record for the SharePoint server to the new zone, double-click the new zone to
Right-click in the detail pane of the console, and select New Host (A) from the pop-up menu.
In the dialog box, enter the machine name of the SharePoint server in the Name field. In the IP
Address field, type the IP address of your SharePoint server.
What about the two check boxes at the bottom of the dialog box? I do have a reverse lookup
zone, and email servers often use reverse lookup to confirm legitimate server addresses, so I
am going to put a check mark in the Create Associate Pointer record. However, in this example,
I don’t want just any authenticated user to update the record, so I am going to leave that option
deselected. To add the host record to your new zone, click Add Host.
(If your environment requires it, you can add a cname or alias record to map the new domain
name to the SharePoint server instead of a host record. That means the MX record will have to
refer to the server in its native, internal domain.)
A pop-up will tell you the host was added successfully. Close that pop-up, and click Done to
close the New Host dialog box.
You now need to create an MX record for the SharePoint server. Right-click in the details pane,
and select New Mail Exchanger (MX) from the pop-up menu.
In the FQDN field, enter the name of the host record you just created. My example is spf1.
dem0tek.com. You can set the mail priority if you’d like. My example uses the default of 10.
When you’re done, click OK. Your DNS server now knows what to do with requests for email
addressed to your new domain alias.
