Universally Located Host Agent

      A mechanism is described which permits host agents (gateway
processes) to be arbitrarily located and conveniently relocated in a
network topology.

      This invention permits arbitrary location of a gateway service.
It is achieved by logically assigning the path from an originating
user to the target host agent for further distributing. Specifically,
the host agent (a process dedicated to providing a gateway service)
is logically defined at a mail server as a name and a location. The
location is the node identifier (NODEID) of the server where the host
agent resides and the name identifies the specific host agent at the
target location. The name is required because more than one type of
host agent may be running on any server machine. The location
(NODEID) may be the same as the originating server or may be on a
server connected through a node to node connection or a cluster agent
connection.

      Mail code which routes distributions and status to the target
host agent must be implemented. The routing code interrogates the
destination of the distribution or status. It then determines, based
on the configured host agent and location, where to send it. This
invention discloses a very simple means of moving the location of a
gateway without changing the originating server code and
communications configuration. Only a simple name and server location
is changed. Convenient and simple mobility of a gateway service to
any connec...
