Mailman is a popular mailing list script. Mailing lists are an ideal tool for communication between far-flung participants and can be about anything you want. Mailman allows you to set up a mailing list with a large number of configurable options, such as who is on the list, where mailing lists messages are sent, and whether you include welcoming messages to new subscribers.
The Mailman documentation, which is incorporated into its Administration panel, is clear and helpful, and should be referred to for all questions about using the script. The instructions in this section deal with how to set up, modify, and delete a Mailman mailing list from your CPanel. You can can also refer to the Mailman home page for more information.
Note: It is a good idea to be aware of spam and its definition before setting up a mailing list - refer to Email Filtering for more information.
To add a mailing list:
Click on the Mailing Lists link in the Mail area.
Click on the Add Mailing List link.
Enter the name of the mailing list in the List Name field, the password for the list in the Password field, and the domain it is for from the Domain drop-down list.
Click on the Create button. The list is created in the /usr/local/cpanel/3rdparty/mailman/lists folder.
