Yes. If you send a bounce message for unknown recipients, you get
used for backscatter attacks, where the spammer forges the source
address, sends mail to a false destination address at your site, and
the bounce ends up where they want it to go.
If you send bounce messages arbitrarily, without some fairly heavy
anti-spam checking, you're a part of the spam problem (unwittingly or
not).
