One thing that will help "some" is to make sure you publish SPF records
for your domains.  If the spam recipients have at least a halfway
competent mail admin then their server should not send any bounces to
mails that hard fail an SPF query..

Of course even half competent mail admins seem to be a rare breed these
days so this is only marginally successful.
