Since example.com is just a domain name, routing is irrelevant. In fact
the IP address that example.com points to is valid -- it isn't running a
mail server though. If you choose a name under example.com for internal
use, and that name leaks to the outside world (e.g. in Received: headers)
then confusion may arise during debugging etc. if someone else happens
to choose the same name. It isn't a serious problem; it's more a matter
of etiquette.
