Probably more reliable to configure BATV, which will refuse all
bounces if they are not arriving at a 'signed' address. Immediate
fix for the joe-job problem.
There may be a few mailing lists that break, if they subscribe
your envelope-from, rather than using the headers like most
software does. Nothing a whitelist can't fix if you care that
much.
Search the web for 'exim batv' - there are config examples out
there.
