A system and method for the management of secure electronic correspondences. The system includes at least one directory, at least one domicile server, at least one processing operator and at least one certification operator. The correspondence sessions are opened by a strong authentication procedure comprising the routing of a secret code over a channel different from the session channel and an identifier specific to the current session. In addition, in order to allow the delivery of correspondence to be sent, it is necessary for the validity of the trust attributes of the sender, the recipients and those involved in the document processing chain be certified by the certification operator for the level required for delivery. The compliance of the processing operations with the operator's specifications is checked by sending, acknowledging and returning certification tokens specific to each of the processing steps.
