[Mailman-Users] BATV and Mailman

[Christopher Adams]

Thank you for your replies. I investigate further and found that it
was a Postfix error in configuration. Though I don't understand if
BATV was truly playing a part in it, the server was rejecting
unverified senders, but there wasn't a hash map to indicate verified
senders. I have fixed this.

I based my findings from my search for "prvs=" in Google.

I proposed an alternative that I called Bounce Address Fingerprint Validation which would achieve the same goals but doesn't actually do munging of the Envelope Sender address, but that ran into more than a little resistance from the supporters of BATV.
