Answer
SMTP is the name given to the protocol (or language) that is used to transfer email messages between computers. The language has only ten or so words to reduce bandwidth and improve performance. SMTP stands for "Simple Mail Transport Protocol".
ESMTP, which stands for "Enhanced Simple Mail Transport Protocol" adds many enhancements to the SMTP protocol. These include security, authentication and other devices designed to save bandwidth and protect servers.
GMS supports a large number of Enhanced SMTP options.
