A mailing list is a list of people who subscribe to the periodic mailing distribution on a particular topic. On the Internet, the mailing lists include each person’s e-mail address rather than a postal address. The mailing lists have become a popular way for Internet users to keep up with topics they’re interested in. Many software producers and other vendors are now using them as a way to keep in touch with customers. The following command is used to enable a Mailing list using Plesk command.
