[Mailman-Users] no "pending moderator requests" email warnings anymore

[Charles Stroom]

Hi,

I have used mailman for many years to maintain a small distribution
list for a group of musical instrument makers, called "dehoutblazers".
It has been transferred a couple of times and runs now on a Linux
Opensuse Leap 42.2 server which distributed Mailman 2.1.22.  The list
is purely used via email (no web site), but I do use the
administrative tasks via the web site.

Since a couple of weeks (or maybe longer) there is a problem with
the "attend to pending tasks", for intercepted emails which are
not going through because of the criteria (non-member email, too
large, etc.) I used to receive a message of the mailman, but I am
not getting such messages anymore.  I have been trying to find out
why, but have so far failed.

I tested also some email mailman addresses with the following results.

- the mail list itself works as it should.
My conclusion is that the aliases file is found and used.

- if I send an email to "listname"-request, I get proper replies.

- if I send to "listname"-admin, I do not receive that email, but
instead an email from mailman-bounce to "listname"-owner with my
email attached.

The attached message was received as a bounce, but either the bounce
format was not recognised, or no member addresses could be extracted
from it.  This mailing list has been configured to send all
unrecognised bounce messages to the list administrator(s).

There are pending pending moderator requests in the list
so I tried a manual cron command (as user "mailman"):
""
/usr/bin/python -S /usr/lib/mailman/cron/checkdbs

Nothing happened, the offending emails are not removed, and I did
not receive any email.   With the mail log below

Apparently, the is something wrong with the email message sender
or recipient as formatted by mailman, but to me everything seems OK.
I am the owner and the moderator.

Is there a way to see what mailman is actually transferring to
the postfix program?

I should add that at about the same time I have added a second
mailing list, which behaves similarly.  I am not sure the
erroneous behaviour occurred before, due to, or after that
introduction.  Any help would be appreciated.

Regards,

Charles
