CPanel includes a popular mailing list script called Mailman. 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.
The Mailman homepage is at the following address for more information: http://www.gnu.org/software/mailman/mailman.html
Note: It is a good idea to be aware of spam and its definition before setting up a mailing list – refer to Blocking email for more information.
To add a mailing list:
Click on the Lists link in the Mail Menu area.
Click on the Add 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 in the Domain drop-down list.
Click on the button. The list is created in the /usr/local/cpanel/3rdparty/mailman/lists folder.
