I had not yet considered it. It looks like there is a milter available, but it is unmaintained. I would be a little wary of setting it up, given the lack of maintenance.

Are there other opensource BATV milters?
It's not BATV but it does help filter bogus use of the Null Reverse Path. Maybe this will help some.
Link - SirWumpus/milter-null: Filter legitimate DSN and MDN messages from those generated as a result of spam backscatter.
- https://github.com/SirWumpus/milter-nullI implemented milter-null within the last month on five Postfix systems. It's helped stop enough bogus DSNs / MDNs to make it worth my time to do so.
And Anthony cleaned up his old code and uploaded it per my request. I'd consider that still supported, or at least not abandoned.
Aside: I've had EXTREMELY good luck with Snert milters over the last two decades. Their milter for ClamAV and SpamAssassin are my preferred milters because of the various options that can be put into /etc/mail/access(.db) to alter how the milter behaves for specific senders and / or recipients.
