About two classes of php send mail (looking for a long time ...) ）

Need to use PHP to send mail, do not want to phpmailer so complex, looking for to find, finally found a good, share out, PHP mail send class, a total of two files. The code is as follows:

sent_mail.php

<?php
require_once (' email.class.php ');

$smtpserver = "smtp.163.com";//smtp server
$smtpserverport = 25;/ /SMTP Server port
$smtpusermail = "*********@163.com";//smtp server's user mailbox
$smtpemailto = "********* @qq. com";/Send to WHO
$smtpuser = "*********@163.com"; the user account of the//SMTP server
$smtppass = "********";//smtp the user password for the server
$mailsubject = " PHP test mail system "//Mail subject
$mailbody ="
