He mentioned "not all witht the same domain", which is not entirely
clear. I read it to mean that some of the rewrites are to different
local-parts, but with the domain unmodified. In that case, and especially
if this is followed by virtual mailbox delivery, the domain is a
virtual_mailbox_domain with partial forwarding.
If what the phrase meant was that there are multiple target domains
into which the original domain is rewritten, but no addresses stay
in the original domain, then it is a virtual alias domain.
This is all documented Phil, please read more carefully, and if not sure
what something means, test your understanding in a test configuration that
does not handle live mail traffic.
