$smtp = array(
//1、EHLO,期待返回220或者250
array("EHLO ".$loc_host.$lb,"220,250","HELO error: "),
//2、发送Auth Login,期待返回334
array("AUTH LOGIN".$lb,"334","AUTH error:"),
//3、发送经过Base64编码的用户名,期待返回334
array(base64_encode($smtp_acc).$lb,"334","AUTHENTIFICATION error : "),
//4、发送经过Base64编码的密码,期待返回235
array(base64_encode($smtp_pass).$lb,"235","AUTHENTIFICATION error : ")
);
//5、发送Mail From,期待返回250
$smtp[] = array("MAIL FROM: <".$from.">".$lb,"250","MAIL FROM error: ");
//6、发送Rcpt To。期待返回250
$smtp[] = array("RCPT TO: <".$to.">".$lb,"250","RCPT TO error: ");
//7、发送DATA,期待返回354
$smtp[] = array("DATA".$lb,"354","DATA error: ");
//8.0、发送From
$smtp[] = array("From: ".$from.$lb,"","");
//8.2、发送To
$smtp[] = array("To: ".$to.$lb,"","");
//8.1、发送标题
$smtp[] = array("Subject: ".$subject.$lb,"","");
//8.3、发送其他Header内容
foreach($hdr as $h)
{
$smtp[] = array($h.$lb,"","");
}
//8.4、发送一个空行,结束Header发送
$smtp[] = array($lb,"","");
//8.5、发送信件主体
if($bdy)
{
foreach($bdy as $b)
{
$smtp[] = array(base64_encode($b.$lb).$lb,"","");
}
}
//9、发送“.”表示信件结束,期待返回250
$smtp[] = array(".".$lb,"250","DATA(end)error: ");
//10、发送Quit,退出,期待返回221
$smtp[] = array("QUIT".$lb,"221","QUIT error: ");
//打开smtp服务器端口
$fp = @fsockopen($smtp_host, 25);
if (!$fp)
echo "<b>Error:</b> Cannot conect to ".$smtp_host."<br>";
while($result = @fgets($fp, 1024))
{
if(substr($result,3,1) == " ")
{
break;
}
}
$result_str="";
//发送smtp数组中的命令/数据
foreach($smtp as $req)
{
//发送信息
@fputs($fp, $req[0]);
//如果需要接收服务器返回信息,则
if($req[1])
{
//接收信息
while($result = @fgets($fp, 1024))
{
if(substr($result,3,1) == " ")
{
break;
}
};
if (!strstr($req[1],substr($result,0,3)))
{
$result_str.=$req[2].$result."<br>";
}
}
}
//关闭连接
@fclose($fp);
return $result_str;
}
?>
