Virtual alias domains are domains in which the addresses are aliased to
other addresses, eventually in other domains. Virtual mailbox domains
are domains where the mail is delivered directly to mailboxes. The
difference between virtual mailbox domains and local domains is that
local domains requires the users to exist as real Unix users.

Yes. This would is a virtual alias map.

Not quite. If you do not qualify the addresses in the RHS of the virtual
alias map, $myorigin will be added. Since $myorigin won't necessarily be
in mydestination, the mail might not be delivered to Mr Doe's local
mailbox.
