The Internet-standard Simple Mail Transfer Protocol (SMTP) can be used to transport and deliver messages based on specifications in Request for Comments (RFC) 821 and RFC 822. The SMTP server also includes enhancements that build upon the basic delivery functions of the protocol. There are options available that give you control over the routing and delivery of messages, and that provide secure communications.
