Mark,
...And everyone else who replied, yes, this does indeed look like a DMARC issue. I looked at the help pages and it looks like some things can be changed but from what I gather any changes would likely affect functionality for the users.
I am a member of a different list that munged the FROM header to the list address with the down side that ALL replies had to go back through the list even if it was specific to one individual. Not a great experience just to pick up a few members who had AOL email domains.
I'll forward the help pages to our ISP list admin to see if he has any thoughts on changes that might help but not restrict functionality.
Thanks, Steve

As pointed out in another reply, this is likely a DMARC issue and MM 2.1.34 has settings to mitigate this.
The interesting thing about this occurrence other than losing the name associated with the email address (since the members were unsubscribed not just disabled) is that I NEVER received ANY bounce notifications other than the unsubscribe notification. I find this quite odd and unsettling considering that the list shows that it IS configured to send earlier bounce notifications and I have received them in the past... just not leading up to this latest incident. The typical error message is:
jonxx_dajxxn@yahoo.com jones_dajuan@yahoo.com has been removed from MSing-ride. (disabled address)
That occurred after the users delivery was disabled by bounce and the notices to the user were exhausted. When the delivery was first disabled, (three weeks earlier with default bounce settings) there was a notice sent to the list admins about the disable if the list's admin Bounce processing -> bounce_notify_owner_on_disable setting is Yes.
Also, you can set Bounce processing -> bounce_notify_owner_on_bounce_increment to Yes to be sent a notice when a bounce is received that increments the score.
If one or both of these settings is Yes and you aren't receiving the notices, that's between Mailman's MTA and you.
So I guess that my question is whether or not these types of problems are now endemic to all email lists or if....Our ISP is technically "challenged" and
- Doesn't know how to properly configure Mailman to send out the requested notifications.
Since you got the unsub notice, I'd expect that all requested notices have been sent.
- Continues to get blacklisted for sending SPAM even though they don't.
What are your settings under Privacy options... -> Sender filters for dmarc_moderation_action and dmarc_quarantine_moderation_action? at a minimum, they should be Munge From and Yes respectively.
