Postfix / MailScanner question - per domain relaying

We use an external mail host that relays all of our email to us on domain abc.domain.com. So all email on this domain comes from 1 subnet.
We also have another domain xyz.domain.com which I need to receive email from anywhere for.
In order to tighten things up a bit, I want to reject all mail destined to abc.domain.com that is NOT from the subnet of our external mail relay. Is this possible? Can someone point me in the right direction?
Here is how I picture this:
Reject all mail to abc.domain.com
Allow mail from 220.127.116.11/24 to abc.domain.com
Allow mail from anywhere to xyz.domain.com
Thanks for any insight.
