The characteristics of a subscriber list are the following:

•  The list is made up of subscribers. An individual becomes a subscriber by sending a message addressed to the IMail list server (imailsrv@domain.com where domain.com represents the mail host); in the body of the message, the intended subscriber enters the subscribe command and the list name.

•  Subscribers can post by addressing a mail in the form of listname@domain.com if Use Password and Enable Posters List are turned off.

• If Use Password is turned on, only subscribers with the password can post.

• If Enable Posters List is turned on, only subscribers in the posters list can post.

• If both Use Password and Enable Posters List are turned on, the subscriber must use the password and be in the poster list in order to post.
