How do I create a subdomain email address?

I have SBS 2003 running Exchange.  I have emails setup from our main domain (for example, joe@company.com).  I need to setup new users on subdomain accounts for email only access (jane@sales.company.com).  What do I need to do to create the subdomain and allow subdomain emails to be created.

AquaITDept-

I saw that the subdomain needs to point to the domain. But shouldn't it point to the domain company.com and not mail.company.com?  DNS servers read right to left.

The part that was missing was that the MX needed to point to the same IP that the mail.company.com domain was on.  Once I changed that the subdomain began working (given the time to propagate across DNS servers).

There were a few steps missing which I researched and found.  Gave me a good platform from where to research.
Thanks ICG. Glad to hear you were able to configure.
Cheers!

Glad you got it sorted. The way I usually create MX entries is as follow:
___________________________
Domain.com    MX mail.domain.com
Mail.domain.com MX x.x.x.x (where x.x.x.x is the IP of your mail server)
___________________________

The same would be true for a subdomain MX entry.

subdomain.domain.com     MX     mail.domain.com (providing that it's pointing to the same Mail server)

OR if it's a different mail server you can typically do:
___________________________
subdomain.domain.com MX subdomainmail.domain.com
subdomainmail.domain.com A y.y.y.y (where y.y.y.y is the IP address of another mail server)
___________________________

So it all depends on how your original DNS entries were setup, but I am glad you got it sorted! Happy Mailing!
