Abstract
The invention relates to a method and apparatus for transmitting electronic mail messages in a local network using information of dynamic routing to provide the electronic mail with service of the required type. A message written by means of a user program 24 is sent to a queue dispatcher 25 which sends information on the address of reception and type of service for the electronic mail to unit 26 for determining a message transmission route. Unit 26 for determining a route controls routing table 27, changing it at the request of control unit 28, and transmits information on the network unit which is the point of destination to the queue dispatcher 25. A communication unit 29 transmits and receives electronic mail and data for making up the routing table.
