I assume you mean 2.1.22 and prior versions since 2.1.22 was released less than 2 months ago. > Recently, my CAMRA > Members list (the biggest one with about 700 email addresses) has stopped > sending me a bounce copy and has on two occasions rejected one of my > messages and unsubscribed a large (apparently random) number of the members, > including me one time. I am having difficulty understanding the issue. What exactly do you mean by "rejected one of my messages"? I.e. you sent a message to the list and then what happened. Do you mean you received a rejection notice from Mailman? If so, what did it say. If you mean something else, what? The unsubscriptions were probably due to bounce processing. What are your bounce processing settings? In particular are all the owner notifications turned on and did you receive any notifications? > There is no pattern to the servers involved. Do you mean the domains of the members who were unsubscribed? This could be a DMARC issue. Particularly if only around the time this started, a user or users started posting From: a yahoo.com or aol.com or other address with a domain publishing a DMARC p=reject policy or if you have regular posters in any of the yahoo.fr, yahoo.jp or other 'foreign' yahoo domains as these recently also started publishing a DMARC p=reject policy. Do you have Privacy options... -> Sender filters -> dmarc_moderation_action set to Munge From or Wrap Message? (Your users will probably prefer Munge From) See the FAQ article at <https://wiki.list.org/x/17891458>. > I > reversed the flags individually in the system which worked for some but some > people are still not getting messages although their Config looks normal.

If this is a hosted Mailman, talking with the hosting provider may help. If posts are bouncing, setting Bounce processing -> bounce_notify_owner_on_bounce_increment = Yes may help you understand why. > Note that I am not a computer or software expert and only use basic > functionality. I can understand that and I am not unsympathetic, but even if you are non-technical, it helps a lot to describe exactly what you see. We will try to help, but at some point, the people who administer the Mailman installation may need to be involved -- Mark Sapiro <[email protected]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
