如果把$All的内容再加处理,就可以实现发送MIME邮件了

先把文件内上面程序里的这些内容填进去,如:
var $ host="smtp.sina.com.cn"; //主机
var $port="25"; //端口 一般为25
var $user=" users"; //SMTP认证的帐号
var $pass="users123; //认证密码

然后把这个文件放到你网站下,只要你网站的程序访问的到就行,.
然后要用到发邮件的程序里包含进来 如: include('smtp.class.php');
然后在这个发邮件的程序里用
$mails=new smtp_mail();
if($mail->send("发信人地址","收信人邮箱地址","主题","内容")){
echo "发 送成功!";
}else{
echo "邮件服务器忙,请稍候再试试";
}
