Mark-san,
Thank you very much for your quick response.
I totally understood, and I should have been more careful about what exactly the admindb is. Thanks a million!
Sincerely,
The messages should be visible in the admindb web interface for the mailman list.
Are the messages you mention that emails which sent to mailman@example.com? Could you please let me make sure that the admindb web interface is a page titled like "Mailman mailing list Administration General Options Section", and the mail sent to mailman@example.com can be visible in somewhere on that page. Is this correct? If so I would like to know exactly where that emails are. "Tend to pending moderator requests"?
The page titled "Mailman mailing list Administration General Options Section" is part of the mailman list's admin (not admindb) interface. The admindb interface is the page linked via the "Tend to pending moderator requests" link on the admin pages.
The admin pages have URLs that look like http://www.example.com/mailman/admin/mailman/...
The admindb interface is http://www.example.com/mailman/admindb/mailman
There should also be a large number of files in mailman's data/ directory with names like heldmsg-mailman-nnn.pck. Each of these contains one held message. Also, depending on list settings, there may be so many of these that the admindb CGI times out before it can generate the summary page. In that case, you have to remove some, but don't just rm them.
I will verify if such files are existed in mailman's data/ directory.
On the other hand, is it possible to know/find where that emails are, if I get the output of dumpdb command executing against lists/mailman/config.pck?
No. There is nothing in the config.pck that tells you anything about held messages. Information about the messages is in lists/mailman/request.pck, but this is the same information that will be presented much more readably on the admindb page
