One should never say the above without explicitly including the

use_sender
is fairly much broken.

"Never" seems a bit strong. If one controls the server being
called out to
and knows that the sender doesn't matter to that server's response,
then it
shouldn't matter. On the other hand, in that situation, use_sender
doesn't
hurt much, either (it may enlarge caches, or I would just say "doesn't
hurt").
Quite correct. I would say that the use_postmaster option is good
too, as it would help the caching and would work also in cases where
VERP is used (unless the receiver accepts <> for regular local parts
as far as RCPT TO is concerned). Of course this does not work in case
of blacklists on senders at the receiving end, but this would be a
design fault, as the blocking must always be done on the front end.
