哪位大哥推荐一个PHP邮件类啊？

<?php

//smtp服务器的密码

//邮件的类型，可选值是 TXT 或 HTML ,TXT 表示是纯文本的邮件,HTML 表示是 html格式的邮件

//发件人,一般要与您登录smtp服务器的用户名($smtpuser)相同,否则可能会因为smtp服务器的设置导致发送失败

$sender = "";

//收件人

$to = "";

// 主题

$subject = "你好";

$smtp =   new smtp($smtpserver,$port,true,$smtpuser,$smtppwd,$sender);

$smtp->debug = true; //是否开启调试,只在测试程序时使用，正式使用时请将此行注释

$body = "<h1>这是一个用 <font color='red'><b> php socket </b></font> 发邮件的测试。

   支持SMTP认证！</h1>

";
