yes. configure filtering "as usual", but put the
-o receive_override_options=no_address_mappings
in the "after the filter" smtpd listener, not in the "before the filter"
as is usually done.
More generally, this option should be set in all smtpd listeners in a
chain, except in the one where you want address rewrite. (you don't want
rewrite twice, because it may cause duplicate delivery).
