That's a 4-year old code base. It was unfortunately not possible
for me to release Postfix with all the features that you might need
all at once.

It's unusual enough that 4-year old Postfix doesn't do address munging
before recipient validation (though some MySQL plumbing can do the
job if you can ignore the @domain portion, as suggested by Noel).
Analogous to Noel's suggestion, one possibility is that you list
bare usernames (without @example.com etc.) in relay_recipient_maps.
It's not documented, but I could add that note since the behavior is
not going to change.
