Abstract :
The paper describes a protocol for Secure E-Mail Infrastructure for establishing trust between different domains in order to protect mail servers from spam messages. The protocol uses messages for trusted interactions between intra and inter E-mail domain components, Secure E-mail (SEM) servers and Secure Mail Infrastructure (SMI) servers. In addition, the protocol validates E-mail addresses thus guaranteeing to the recipient that the E-mail is coming from a trusted domain. We also use XACML-based authorization policies at the sending and receiving servers, enforced by associated Policy Enforcement Point (PEP) servers at SEM servers, in order to provide a complete protection against spam.
