they are completely separate other than the subnet.
There have been no configuration changes at any level.

Is is possible that exchange 5.5 doesn’t recognize a domain with a hypen in the name? (area-audobon.com)?

Is the communications totally internal or internal to external?
Do you use a gateway service in a DMZ that acts as a relay?
Has anyone changed this gateway? Any network changes (ACL, NAT, etc.)?
