调用示例：
smtp('smtp.qq.com');           //邮件发送服务器 
 $smtp->pors(25);                      //邮件服务器端口 
 $smtp->login( '[e-mail]');     //邮件服务器登录用户 
 $smtp->pass('您的邮箱密码');             //邮件服务器登录密码 
 $smtp->mails( '[e-mail]');    //邮件接收人 
 $smtp->from( '[e-mail]');      //邮件发送人 
 $smtp->come( '[e-mail]');  //接收邮件回复地址 
 $smtp->title('这是一封邮件测试地址邮件');  //邮件主题 
 $smtp->body('这是一封邮件测试内容邮件');   //邮件内容 
 $smtp->send();                        //发送邮件
 echo $smtp -> Mesg === true ? '邮件发送成功' : $smtp -> Mesg; //邮件发送结果
