Earlier this month I email this list with issues I've had approving/discard messages via the web interface (see below).

After digging around I've found that I maybe experiencing some kind if config corruption in pck files under /var/lib/mailman/lists/mailman When looking through the smtp-failure log I noticed errors "Sender address rejected: Domain not found" and it appears something has or is appending the text "new-" to the beginning of the domain we use. Further investigation shows that "new-" is appended to the domain in the config.pck, config.pck.last & config.pck.safety files. I have no idea how this got into the files but it appears to me the source of problem. I have reviewed the configuration of mailman via the administrative web interface and it all appears correct (no arbitrary "new-" text) . This is not a new installation of mailman and has been in use for many years. This issue seemed to have started occurring in July of this year. Any help would be greatly appreciated.

A few weeks ago are started experiencing problems with approving and/or discarding messages. I am also unable to add/delete users to the list but messages from approved list members work fine. I suspect either some file has become corrupted or a permissions issue.

I also see entries such as the following in the errors logs:

Aug 04 06:47:41 2019 (20501) No such list "aewa<[55": Aug 04 11:05:13 2019 (28708) No such list "aewa<https:":

I have run check_perms with no problems found.

Has anyone see this before or can suggest a solution?
