A mailing list may contain any number of members' e-mail addresses. An email sent to the list is automatically forwarded to all its members. In the mailing list’s settings is defined who can send e-mails to recipients on the list. Thus, it can be configured to allow only subscribers to send e-mails to their list. It is possible as well to allow anyone to send an e-mail to a list, which, of course, will be distributed only to list members.
