Mailman Pickle files!

If you’re running a cPanel server with mailman you may find that some of your users want to access the details of their Mailing Lists (Usernames/Passwords for single sign-on style reasons).

The Pickle file can be found here:
/usr/local/cpanel/3rdparty/mailman/lists/listname/config.pck

and,

python /usr/local/cpanel/3rdparty/mailman/bin/dumpdb
/usr/local/cpanel/3rdparty/mailman/lists/listname/config.pck

Will produce an output that you can simply redirect to the users home directory for them to parse and use as they wish.
