To understand open relay SMTP, some definitions first:
OPEN RELAY: (sometimes also referred to as a third-party relay) is a mail server that does not verify that it is authorised to send mail from the email address that a user is trying to send from. Therefore, users would be able to send email originating from any third-party email address that they want.

SMTP is a Simple Mail Transfer Protocol, and the objective of SMTP is to transfer mail reliably and efficiently. SMTP is independent of the particular transmission subsystem and requires only a reliable ordered data stream channel. An important feature of SMTP is its capability to relay mail across transport service environments. A transport service provides an interprocess communication environment (IPCE). An IPCE may cover one network, several networks, or a subset of a network. It is important to realize that transport systems (or IPCEs) are not one-to-one with networks. A process can communicate directly with another process through any mutually known IPCE. Mail is an aplication or use of interprocess communication. Mail can be communicated between processes in different IPCEs by relaying through a process connected to two (or more) IPCEs. More specifically, mail can be relayed between hosts on different transport systems by a host on both transport systems.

OPEN RELAY SMTP: Email is transported across the Internet via Simple Mail Transfer Protocol (SMTP). SMTP relays email from server to server in route to your mailbox. When email arrives at your ISP's server, it is stored there until you download it via Post Office Protocol (POP3)
