The web mail systems haven't solved that problem, so I don't think we
need to, either.  Any forwarder of any size has FBLs set up, so it will
get reports about forwarded mail via the target system.  That works OK
for me.

Short of a mythical global reputation system, I don't see how one could
divert reports to forwarders without also diverting them to spammers who
pretend to be forwarders.
