HTH ..or at least gets some others thinking on a way to help ..:)
given that I think any bounced message would contain in the subject the word "delivered" ( as in "could not be" .) might it not work if you auto forwarded all incoming to gmail ( did I just suggest the GORG )..and possibly you could set their customisable filters to reject any mails which include your own "compromised addy in the from part of the header" ..
maybe this would even work on your own system ..by definition ..any mail "bounced" at you will have your own addy in the header at a point where normally it wouldn't be ..and you wouldn't need to translate your own addy ..
see where I'm going ?
there should be a common element ( string ) to all the headers that are bouncing to you ..that is not present in normal incoming headers to you..so you'd have to filter by headers ..presumably a bounce will have your addy twice in the header..and a real incoming will only have your addy once in the header
