wp使用socket和smtp代理发送评论回复邮件
吵吵   2011-08-08  阅读：5,631

那天在帮老师用一个客户留言的页面，客户通过先写表单传送过来留言内容等，然后老师想用邮件发送到它的邮箱中去，以方便及时回复。本来想是个很简单的问题，不想他的空间不支持mail()函数，那就只能用socket发了，用smtp协议来发吧。网上找了很多php的类，发现用不了，不过后来找了半天还是找到了一个。

后来就用126邮箱来代发我博客上的评论回复了，这么做的原因一是本身的mail函数是由服务器上的邮件服务器代发的，如果再天上自己的邮箱，那么收到邮件后就会由于发件人和发件邮箱不一致而成为垃圾邮件。第二就是这个邮件是回复不了的，及时别人回复了，也是服务器收到了，而你看不到。总而言之，用自己的126邮箱来代发还是不错的，除了有点慢之外。
好了，这个是邮件发送的类：

接下来的就是一个例子了，就是我们的博客评论回复邮件通知的代码，可以做个参考。

/* 上面的判斷式,決定發出郵件的必要條件:
($parent_id != '') && ($spam_confirmed != 'spam'): 回覆的, 而且不是 spam 才可發, 必需!!
($to != $admin_email) : 不發給 admin.
($comment_author_email == $admin_email) : 只有 admin 的回覆才可發.
可視個人需求修改以上條件.

    add_action('comment_post', 'comment_mail_notify');

    上面的代码仍到任何可以执行中就ok了，如主题的functions.php中。
