Control of message to be transmitted from an emitter domain to a recipient domain

An entity in an emitter domain for controlling a message to be transmitted by a sender terminal connected to said emitter domain, to a recipient domain, the sender being linked to a sender domain, said entity being adapted for:

• transmitting a notification request including data from said sender domain to said recipient domain, after receiving said data transmitted by said sender domain as a result of an authentication of said sender of said message by said sender domain, so that in response to receiving said notification request, said recipient domain is adapted to transmit a notification confirmation request including said data to said sender domain, and
• transmitting a notification confirmation response to said recipient domain in response to said notification confirmation request transmitted from said sender domain to said emitter domain, if the data included in said notification confirmation request are identical to the data contained in said notification request and transmitted from said sender domain as a result of said authentication of said sender.

An entity in a sender domain for controlling a message to be transmitted by a sender terminal connected to an emitter domain, to a recipient domain, the sender being linked to the sender domain, said entity being adapted for:

• transmitting data from said sender domain to said emitter domain, as a result of an authentication of said sender of said message by said sender domain, and
• transmitting back a notification confirmation request including said data to said emitter domain, if the data included in said notification confirmation request are identical to the data transmitted from said sender domain as a result of said authentication of said sender, said notification confirmation request having been transmitted from said recipient domain to said sender domain in response to a notification request including the data transmitted from said emitter domain to said recipient domain as a result of said authentication of the sender, so that said emitter domain is adapted to transmit a notification confirmation response to said recipient domain.

A computer readable medium or storage device storing a computer program for causing a data processor arrangement in an emitter domain to control a message to be transmitted by a sender terminal connected to said emitter domain, to a recipient domain, the sender being linked to a sender domain, said computer program, when executed in said data processor arrangement, causes the processor arrangement to perform the following steps:

• transmitting a notification request including data from said sender domain to said recipient domain, after receiving said data transmitted by said sender domain as a result of an authentication of said message of said sender by said sender domain, so that in response to receiving said notification request, said recipient domain is adapted to transmit a notification confirmation request including said data to said sender domain, and
• transmitting a notification confirmation response to said recipient domain in response to said notification confirmation request transmitted from said sender domain to said emitter domain if the data included in said notification confirmation request are identical to said data transmitted by said sender domain as a result of said authentication of said sender.
