Hello all,
I have had a couple of list subscribers fail to post message to their lists. I tracked down the logs and this seems to be the common theme. I Googled prvs= and found info on BATV. Does Mailman not play well with this or am I not quite understanding what this means?
<prvs=288122D8EB=email@anywhere.com>: Sender address rejected: undeliverable address: host senders.mailserver.com[xxx.xx.xxx.xx] said: 550 5.1.1

Where is this message? Is this from a DSN returned to the subscriber for his failed post? Is this a message in your outgoing MTA log or a DSN regarding a failed delivery to the user?
Is the user's post rejected before reaching Mailman or is mail from Mailman not being delivered to the user?
Please clarify and describe in more detail exactly what's going on?

For those who are not familiar with this term, they should see the Wikipedia page at <http://en.wikipedia.org/wiki/Bounce_Address_Tag_Validation>.
Suffice it to say that BATV has more than a few problems. 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.
And when combined with things like VERP, it can really screw things up.

I think some critical information is being lost here. We need to see the entire error message being generated, and we need to know more information about how this system relates to the Mailman installation, etc....

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.
