You had me convinced that PermError was better than nomatch. Mainly
because literally putting a:example..com is a plausible typo that should
get a PermError, rather than silently failing to match. You made the
case that no legitimate sender should generate a PermError via macros.
(If the policy wants to accomodate braindead senders, don't use %{h}.)
My only reservation is that spammers could generate PermError via macros.
I was considering posting an auto-note to postmaster in case of PermError
in addition to a DSN, but PermError from macros would discourage that.
