不需要邮件服务器，不使用mail内置函数，一个类就搞定，利用php教程mailer类我写了一个自定义函数 sendmail() ，very实用！

以前也在几个php论坛上发表过这个发邮件的函数，今天再发，因为today要附上使用例子，如果你还不会用，那就要补补php基础课了。

  1.准备文件 sendmail.class.php文件、phpmailer类     下载  

2.下载后，解压 phpmailer.rar 到服务器的任何目录下

3.打开 sendmail.class.php ，修改如下（浅黄色部分是必须 要修改的变量值）

 // 以下 5 个变量值必须据实修改
 $host     = '61.183.41.172';
 $username = 'admin@php95.com';
 $password = "******"     
 $from     = 'admin@php95.com';
