An electronic system for indirect intercommunication messaging includes at least one central processing unit acting as a server, and one or more user terminals adapted to be bidirectionally connected to the central processing unit, wherein each one of the user terminals includes components for preparing and sending to the central processing unit a request for contact with another one of the user terminals, the contact request including data relating to at least one interaction genre and to the identification of the other user terminal; components for receiving and displaying a contact request sent by the central processing unit and coming from another one of the user terminals; the central processing unit includes components for receiving and storing the contact requests coming from each one of the user terminals; comparing the data contained in the contact requests; sending to a pair of the terminals the requests for contact with the other terminal of the pair only if and when coincidence is verified between the interaction genre data of the contact requests and the terminals have been mutually identified, so that the contact between the pair of terminals can only be activated upon the coincidence verification.
