CentOS5.5下PostFix邮件系统配置，采用比较简单的yum来进行安装，当然也可以用源码进行编译安装。

测试php邮件发送
[root@dyq www]# vim mail.php
<?php $to = 'kiccleaf@163.com'; $subject = 'the subject test'; $message = 'hello！测试用例！'; $headers = 'From: leaf@kiccleaf.com' . "\r\n" . 'Reply-To: leaf@kiccleaf.com' . "\r\n" . 'X-Mailer: PHP/' . phpversion(); mail($to, $subject, $message, $headers); ?>
打开浏览器http://youip/mail.php 再查看邮件是否已经收到邮件
也可以用foxmail客户端进行测试。
