Abstract:
1. A method performed by an access point of a receiving domain for processing a communication sent from a sender in a sending domain to a recipient in the receiving domain, the sending domain being different from the receiving domain, the method comprising: receiving from an access point of the sending domain the communication sent from the sender to the recipient in the receiving domain via the access point of the sending domain; receiving from the access point of the sending domain along with the received communication a trust level associated with the sender, the trust level indicating confidence that the sending domain has that the communication will be wanted by the recipient of the communication; determining a confidence that the receiving domain has that the trust levels received from the sending domain accurately reflect whether senders in the sending domain are sending wanted communications; determining whether a trust criterion is satisfied based on the received communication and the received trust level, the trust criterion factoring in the determined confidence that the receiving domain has in the sending domain; and processing the received communication based on whether the trust criterion is satisfied such that the communication is sent from the access point of the receiving domain to the recipient when the determined trust criterion is satisfied.
