7.1 The Event Manager

     The event manager has two modes. The first is the view mode,
     which is self explanatory. The second mode is the edit/create
     mode. It will now be described.

     Tag (T)         The event "ID". A letter from A-Z or @. The @
                     event has special meaning and is described later.
                     X is used for eXternal events, all other letters
                     are used for mail events. Which letter you use is
                     not important. They could correspond with the
                     time of day, N for Night, E for Evening, D for
                     Day, etc. The event tag is used to associate an
                     event with a schedule block in the route file
                     (see "Mail routing").

     Days            The days you want the event to be active on. The
                     @ event is active on all days.

     Modifier (M)    You can define a start time for the @ event. It
                     is not used to control the start of the @ event.
                     It can be added, subtracted, or ignored, when
                     calculating the actual start time of other
                     events.

                     If the modifier for an event is +, the start time
                     of the @ event is added to the start time of the
                     event.

                     If the modifier for an event is -, the start time
                     of the @ event is subtracted from the start time
                     of the event.

                     If the modifier for an event is *, the start time
                     of the @ event is ignored and not used to
                     calculate the actual start time of the event.

                     This is very useful when it is time to switch
                     between winter and summer time. Instead of having
                     to manually go into each event and define a new
                     start time, you could change the start time of
                     the @ event and the start time of all other
                     events will be changed.

                     Let us assume that you have an event (tag=E) that
                     starts at 08:00 in the morning with a modifier of
                     +. Your @ event has a start time of 01:00. Since
                     the modifier was + (add), the start time of @
                     (01:00) will be added to the start time of the E
                     event and the result will be that event E starts
                     at 09:00. If you change the modifier to -
                     (subtract), the start time of event E will be
                     07:00 (08:00 minus 01:00). If you set the
                     modifier to * (ignore), the start time of E is
                     not affected.

         Start time  Defines the start time of an event. See Modifier
                     (above) for an explanation on how this can be
                     affected.

         Length      Defines the length of the event. External events
                     (X) always have a length of 00:01 (one minute).

         Errorlevel
                     For external (X) events, this defines the
                     errorlevel that the Mailer (FD) will terminate
                     with.

                     For mail events, this defines the errorlevel to
                     exit with if mail is received (and the Mailer is
                     triggered to exit). If the errorlevel field is
                     set to zero, the default MAIL RECEIVED errorlevel
                     will be used.

                     You may use any value in the range 31-255.

         Min.cost    Defines the minimum cost of messages that should
                     be qualified (see "Mail routing").

         Max.cost    Defines the maximum cost of messages that should
                     be qualified (see Mail Routing). A value of -1
                     forces FD to ignore the cost of messages.

         Behavior    Defines the behavior of the event. Mail events
                     and external (X) events have different behavior
                     options, this is described later.

         Retry delay
                     Defines the delay (in seconds) the Mailer should
                     wait between placing outgoing calls. A value of
                     zero means that you want the Mailer to use the
                     default delay (described earlier).
