Once a mailing list has been created in MDaemon login to MDaemon Remote Administrator as a Global Administrator (Accounts -> Account Manager -> [account-name] -> Administrative Roles) and choose Mailing Lists -> [listname] -> Edit -> List Administrators. Here you can give a user list admin permissions:
If that user then logs into MDaemon Remote Administration they can administer the list and add/remove members, set notifications, etc via Mailing Lists -> [listname] -> Edit.
