I am using address rewriting for all addresses @rath.org:

 - Every outgoing mail has its envelope from rewritten to
   @bounce.rath.org, a domain name that isn't used for anything else
   
 - Bounces (i.e., mails coming with envelope from <>) send to
   @rath.org are rejected as backscatter.

 - Mail to @bounce.rath.org is rewritten back to @rath.org

 
So far this has worked perfectly. But of course, there might be
software that sends bounces to the From: or Reply-To: address. So if
you want to use this not exclusively for your own address, you
probably want to be careful.

HTH,
