<?php

$smtp="";
$port=25;
$from="president@whitehouse.gov";
$to="ton_mail";
$fp = fsockopen($smtp,$port, &$errno, &$errstr, 30);

if($fp)
{
	$request = "HELO Googleman\n\n";
	echo '<br/><br/>ask:' . $request;
	fputs($fp,$request);    
	echo '<br />'.fgets($fp,1024);   

	$request = 'MAIL FROM: <$from>\n\n';
	echo '<br/><br/>ask:' . $request;
	fputs($fp,$request);    
	echo '<br />'.fgets($fp,1024);   

	$request = 'RCPT TO: <$to>\n\n';
	echo '<br/><br/>ask:' . $request;
	fputs($fp,$request);    
	echo '<br />'.fgets($fp,1024);   

	$request = "DATA\n\n";
	echo '<br/><br/>ask:' . $request;
	fputs($fp,$request);    
	echo '<br />'.fgets($fp,1024);   

	$request = ".\n\n";
	echo '<br/><br/>ask:' . $request;
	fputs($fp,$request);    
	echo '<br />'.fgets($fp,1024);   

	$request = "quit\n\n";
	echo '<br/><br/>ask:' . $request;
	fputs($fp,$request);    
	echo '<br />'.fgets($fp,1024);
