You don't need a lock file on /dev/null, so the trailing ':' on the
flags is unnecessary.

If this recipe works, more power to ya. The canonical way is to use
the ^FROM_DAEMON macro:

  :0
  * ^FROM_DAEMON
  /dev/null

but that may be more than you need.

You might also look into the root cause of this; perhaps something
like SPF on this domain could help mitigate the problem (if this is a
joe-job issue), since domains currently rejecting the mail w/ a bounce
might not even accept the mail in the first place if an SPF record
were present.

Also, know that rejecting all bounces includes legitimate bounces that
your customer might want to know about (e.g., misspelling Mom's email
address) and you'll get no feedback from those. If they understand
that risk and accept it, this recipe above will be fine.
