If you are talking about bounces as bounce messages generated by your
system, it's a sub-optimal solution ;-)

The message is dumped to /dev/null, thus lost. If this is, what you
want, then it worked. (But the message passed through the wire into your
system.)

Better solution would be to *reject* mails to unknown users at SMTP time
already. This does not generate bounces in your system, and if the
sender just mistyped your address, there is some good chance, that the
senders system generates a bounce to the sender, informing him/her bout
the mistake. (And the side effect is, that the message gets rejected
already at "RCPT TO", thus not passing any DATA to your system.)
Make sure, that your (local user) router generates an error for unknown
users and that your recipient ACL has a 'require verify = recipient' or
something similar.
