In this example, the user sue@example.com sets up a mailing
    list named sample-list. The mailing list file is the file
    D1:[SUE]SAMPLE.DIS and its contents are shown in below. The
    commands used to set up the list are also shown below. Mail is
    posted to the list by sending messages to the address sue+sample-
    list@example.com.

    The use of the AUTH_LIST named parameter in the alias declaration
    restricts the list such that only members of the list can post
    to it. Two positional parameters, ERRORS-TO-ADDRESS and COMMENTS,
    are also specified. The ERRORS-TO-ADDRESS parameter specifies
    that error messages associated with the list should be sent to
    sue@example.com; the COMMENTS parameter generates a Comments:
    header line reading "Sue's sample list". which will appear in
    each posting to the list.
