Method for Communicating Excessive Gateway Cycle Time to Senders

      Provided is a method for indicating to a distributing user that
a priority distribution may not be delivered to a recipient list in a
priority manner because of an intervening polling gateway.

      Currently, many gateways cycle asynchronously in order to
communicate mail and status between systems.  Ideally, the gateway
should communicate in a real time manner.  However, many operating
systems do not support multitasking environments, and processes must
perform polling of shared data areas or databases.  To further
complicate matters, many non-multitasked products have been ported to
multitasking environments with the same shortfall design and
methodologies used for the original design.  A method is needed for
communicating an excessive delay to a sender, particularly when a
priority delivery item is sent.

      Provided is an automatic probe in a receiving mail router
system for determining attributes on distributions which are sent
with priority.  Attributes were intended for interrogation, thereby
eliminating the need to poke into the distribution content which
would be a performance problem.  Upon determination of a priority
distribution and a target gateway which performs polling, a
determination is made for how long a delay will occur before the next
gateway poll.  If the delay exceeds a reasonable amount of time, a
special status is returned to the sender which indicates the...
