php实现的邮件发送类，二种方式：
smtp方式与mail函数方式。
代码：

?>调用示例：
<?php
include "sendmail.class.php";
$Mail = new sendmail();
// Set congif
$Mail->SendMailVia = 'smtp'; // Send via smtp server or mail function
$Mail->smtp_host = 'mail.myhost.com';

$Mail->smtp_user = 'user@myhost.com';

// 例1 (mail from me)
if($Mail->Send('mymail1@mydomain.com; recipient2 name <recipientmail2@mydomain.com>,"recipient name" <recipient@mail.com>',
'My subject','My message here.'))
{
echo '邮件已发送!';

else

// 例2 (mail from me)
$Mail->mail_to = 'mymail1@mydomain.com; recipient2 name <recipientmail2@mydomain.com>,"recipient name" <recipient@mail.com>';

// 例3 (mail from another user: example user2@site2.com)
