Detailed Description

The Simple Mail Transfer Protocol (SMTP) as defined by RFC821 is the standard way of sending and transfering e-mail on the Internet.

This simple example implementation is intended as an example of how to implement protocols in uIP, and is able to send out e-mail but has not been extensively tested.
