I suspect a considerable underestimate.  amdcad.amd.com is not directly
connected to the internet (we have an MX forwarder; thanks ames!), but
is in the UUCP maps.  The 619 machines in the .amd.com domain are not
listed in the uucp maps (much to the moderators' relief, I'm sure :-).

amdcad accepts both user@site.amd.com and amdcad!site!user style addressing.
As far as I know we're RFC-822 compliant, and use smail to interface
cleanly to the UUCP world.  Writing off connectivity to 15,000 sites that
use ! just so you can talk to 100,000 sites that use @ doesn't strike me
as a good idea.  We want to talk to all 115,000.

Entirely too close to the truth, I suspect. :-(
