Stop plugging a recipient-side cost-shift scheme that you're directly
involved with as some sort of panacea.  BATV has benefits, as do other
schemes, but you're still fixated on it as being the end-all, be-all of
forgery prevention -- by making third parties do the dirty work and letting
the instigators off the hook.

By putting the costs on the shoulders of third parties, you're putting
yourself squarely on the side of the spewing hosts, and being as ignorant as
the admins running the anti-malware products on those hosts.  For shame.

Until you get the point that you're putting the burden on people that have
nothing to do with the problem that started this long thread (anti-malware
notices to forged senders), and your first priority should be stopping that
spew at the source BEFORE asking uninvolved third parties to help, you're
going to continue to look like the self-absorbed crack smoker you've made
yourself out to be.
