preventing mail from being received from specific domains

I looked in the online FAQ at for Post.Office to see if there
was a way within the program to block mail that's sent from domains (or IP
subnets) such as "", "", and "" but
there's no means of doing it. Does anyone have any tricks up their sleeves
that might work?

Our connection to the net is through a Cisco 2501 router, but we do not
have access to it to change any settings (owned and maintained by Sprint
Advanced Network Systems, here in town).
The next box in line is an HP AdvanceStack Switch 2000.
The mail server is running Post.Office 2.0 (will be 3.1 in a few days)
running on NT 4.0 SP3 (PDC).

Any ideas?
