If without rewriting, that's a "relay domain". If addresses are
always rewritten to another domain (ala the model of pobox.com),
then its a "virtual alias domain". Take the time to understand

Not a problem, virtual aliases are global, pick whichever model
is best for any users that are not rewritten to another domain.
