In situations where mail is forwarded outside the environment that
supports the local recipient delimiter (e.g. Postfix->Exchange):
I set:
propagate_unmatched_extesion = canonical
overriding the default:
propagate_unmatched_extensions = canonical, virtual
that way, mail arrives to the right recipient on the destination system.
The recipient can still apply filters on the headers, but loses the
extension in the envelope, which is typically not tragic.
