首先，不建议使用 mail 函数直接发送email,服务器支不支持先不说（并不是所有供应商都愿意开放25端口，这种容易被滥用的接口），国内的反垃圾机制基本上你这就被当垃圾处理了，甚至垃圾箱里都没有，直接过滤掉。所以一定要使用SMTP。

以163为例，申请一个163邮箱，打开SMTP服务
下载一个配置类 http://files.cnblogs.com/file...

    require_once("email.class.php");
    $smtpServer="smtp.126.com";
    $smtpServerPort="25";
    $smtpUserMail="[e-mail]";
    $mailTo="[e-mail]";
    $user="wangkyx";
    $mailPwd="{发送邮箱密码}";
    $mailTitle="邮箱标题";
    $mailContent='<h1>测试邮件 001</h1>';
    // 邮件格式 （HTML/TXT）
    $mailType="HTML";
    // true表示是否身份验证
    $smtp=new smtp($smtpServer,$smtpServerPort,true,$user,$mailPwd);
    // 是否显示调试信息
    $smtp->debug=false;
    // 返回 bool
    $state=$smtp->sendmail($mailTo,$smtpUserMail,$mailTitle,$mailContent,$mailType);
    var_dump($state);
    
    （邮箱代码这段是百度抄的，这里是25端口是个示例，实际上主流邮箱都会提供SSL协议的端口）
    
    $mailContent 就是发送的内容，你可以把呀发送的东西写成HTML 的格式，把内容放进去（强烈建议行内样式），就像正常页面那样。
