<h1>SMTP E-mail sender<br>
<small>
[<a class="el" href="a00143.html">Applications</a>]</small>
</h1><hr><a name="_details"></a><h2>Detailed Description</h2>
The Simple Mail Transfer Protocol (SMTP) as defined by RFC821 is the standard way of sending and transfering e-mail on the Internet.
<p>
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.
