Linuxsir的弟兄们，你们好。我在 Ubuntu server 7.10 下用 LAMP 搭建了一个

wordpress博客和discuz论坛，但是wordpress的评论邮件和discuz的注册用户邮件发送

都不起作用。特向各位弟兄请教。详细情况如下：

1、用sudo apt-get install sendmail mailx 直接安装，没有修改任何设置文件；

#############################################################################

##################################

2、用 mail -s "test" username@localhost < "test.txt" 能够给本地用户发送邮件，

但是用同样的命令向一般的邮件（如：username@tom.com）发送邮件却收不到；

Jan 13 11:56:40 ubuntu sendmail[9053]: My unqualified host name (ubuntu)

然后，系统给本地用户发了一封邮件，用mail读取内容如下：

6、我觉得可能是tom.com 认为我们发的邮件是垃圾邮件给屏蔽了，但是我们的IP是才用

的，不应该进入他们的黑名单。

我怎样才能使网站的wordpress 博客和 discuz 论坛的系统邮件发送功能正常呢？只需

要能够正常发送这些程序的通知邮件。不必成为一个全功能的邮件服务器。

谢谢。

大站一般会对接到的信件做DNS反解，不成功就不接受。参考
http://bbs.5dmail.net/thread-8907-1-1.html

[littlebat]

谢谢 ccan30 ，您介绍的文章很详细。我试试看看。如果确认我的 sendmail 配置没有错的话，我试试域名设置。
