I have switched the ip address of our mx record since we started hosting our
own email. Since I still have several end users that work remotely and get
their email via POP3 account, I would like to add the mail.mydomain.com to
my dns server. This way they can get their mail when they are in the
office. Right now if I ping mail.mydomain.com it points to the outside ip
address. My active directory domain. abc.local. and I have several other
mail.domains.com. How can I add them to my dns server? Thanks for any help
that you can provide.

Add it to your server. What stops you?

If you running a Shadow (or Split) DNS* setup, then you must add all
external
records you wish your users to see (whether using same value or different)
to the internal DNS server (set) manually.

*Shadow DNS is a setup where you run two seperate zone server sets that
have the same name. One for the outside world to use that contains only
externally reachable resources with public address, and another with all the
names and address (whether internal or external) of your zone for servicing
the internal clients.

Shadow DNS is really two separate zones that happen to have the same
name -- they will not replicate, and so any common records must be added
manually to both zones.

The simplest way of acheiving what you want to do is to add a new forward
lookup zone named "mail.mydomain.com" (without the quotes), in that zone
create one new host, leave the name field blank, and give it the internal IP
address. This way, your DNS server takes authority over mail.mydomain.com
and leaves the authority of the rest of mydomain.com on the external DNS
servers.

I take it that would be a primary zone. If I have multiple dns servers,
would I need to create this zone on all the servers?

On the first one it would be Primary. On others you would typically
make it Secondary or AD Integrated on all DC-DNS.
