This seems to work nicely:

|
|md:
| driver = smartuser
| local_parts = mailer-daemon
| new_address = ":blackhole:"

|

I mean really, what possible legitimate reason could there be for
someone to send any important mail to mailer-daemon? Anyone with a clue
will send to root@ or postmaster@, error-bounces either wont happen
(envelope sender = <>), or, in the case of broken MTA which send
error-bounces to From: header address, do you really care to get them?
