Indeed. However, when mail is forwarded (via an alias, .forward
file, or otherwise) to an unqualified user (no domain) then Postfix
appends $myorigin.

The virtual map rewrites any recipient (and appends $myorigin to
an unqualified address). The "virtual.domain whatever: entry is
black magic, otherwise the virtual map is like a global alias table.
