Reset mailman admin password

To reset a mailman admin password on Debian, the easiest way is to locate the mailman's proper bin directory (use dpkg -L mailman), generally: /usr/lib/mailman/bin There, you'll find an executable script called change_pw. Use this one. If you want to change the password of all lists at once, use: sudo ./change_pw --all --password=newpassword Ref: http://www.mail-archive.com/mailman-users@python.org/msg34242.html
