The web interface allows you to set up eight distinct message
    filters: four to identify messages to always keep, the Accept
    filters; four to identify messages to always throw away,
    the Discard filters. The Accept and Discard filters operate
    on envelope and header source addresses, header destination
    addresses, and phrases or words appearing in the SUBJECT: header
    line or body of the message. The eight filters are thus known by
    the names ACCEPT FROM, ACCEPT TO, ACCEPT SUBJECT, ACCEPT BODY,
    DISCARD FROM, DISCARD TO, DISCARD SUBJECT, and DISCARD BODY.

    The web interface also allows you to set up a forwarding address.
    When you have a forwarding address set up, all of your mail that
    you have decided to keep with your Accept filters will be sent to
    that address instead of being delivered to your local account.
    Note that the Accept and Discard filters are applied first,
    and the vacation notice (if any) is also sent first, before the
    message is forwarded.

    The web interface also allows you to set up a vacation notice.
    Set up a vacation notice when you want to send an automatic reply
    to mail messages that you receive. The reply notifies the sender
    that you are on vacation or otherwise away for an extended period
    of time and may not respond to your mail until you return. The
    web interface allows you to enable or disable the vacation notice
    feature, to specify the subject and text that is included in the
    vacation notice, and to set up some advanced options.

    PMDF keeps a history of which addresses it has sent the vacation
    notice to, and does not send another vacation notice to that same
    address unless

    o  you change the text or subject of your vacation notice

    o  you enable the vacation notice feature after it has been
       disabled

    o  the number of days that you specify in the web interface has
       passed

    Note that PMDF will not send the vacation notice if it determines
    that the message was received through a mailing list.
