How was Mailman installed? If it is a virtualmin package, see the FAQ at

equally to virtualmin.

The admindb CGI should always return a page whether or not there are
pending requests. What do the web server logs say? Pending request
reminders should not be sent if there are no requests. See the FAQ at

Check your MTA logs and compare the Received: headers of the multiple
copies for clues on where the duplication occurred.

Look at Mailman's logs for problems.
