The solution is to not forward spam to outside accounts. That
means your server must not accept the spam in the first place.
Search the list archives and the postfix docs for general
Forwarding mail off-site without generating backscatter isn't
an easy problem to solve. The "obvious" solution of not
sending bounces is the wrong solution since it breaks mail
The real solution is an SMTP proxy that forwards the mail in
real time so that mail not accepted by the various downstream
servers is never accepted by your server. Unfortunately
postfix (or any MTA I'm aware of) can't do that.
