有几个IREDMAIL的疑问：

1、如果想要把IREDMAIL所有的配置及用户数据（邮箱信息，邮件信息等）进行备份，都需要备份哪些地方呢？

我现在用的是iredmail+ldap，请详细说明下，如有操作文档，请贴上连接谢谢!

2、如果服务器DOWN，迅速将新的服务器重新搭建起来，请问如何进行备份数据的恢复呢？

本人是新手，在网上没有找到相关文档，请专家指教。先谢了。

发往一个域名的邮件总是退信（目前只发现这一个域名退信），请大家帮忙分析一下，先谢谢，（这个邮箱是老板经常发的）。

以下是退信内容：(yao@111.com.cn发送到jyin@cynovo.com)

我还没做过TXT及DKIM记录，是否会这个原因？邮件服务器现在对GMAIL SINA等收发正常。谢谢大家了。

各位大侠们您们好，有个问题请教一下。
可以正常登录iredadmin，但是点击用户的时候，就跳出如下：（点击邮件域等连接正常）

(False, 'msg=%7B%27desc%27%3A+%22Can%27t+contact+LDAP+server%22%7D')

我检查了服务器上sldap服务正常在运行。如下：

cynovo@mail:~$ service slapd status
OpenLDAP is running

现在邮件收发正常，请各位大侠多多帮助，急，在线等!

发现很诡异的问题，发送邮件maillog日志显示成功，但对方收不到。

如果是对方先发邮件给我，我在发给对方，就能收到了。

请教给位大侠，以前有没有遇到过类似的情况？怎么解决？谢谢

还有一个问题，发sina邮箱发送不了，我已经在ISP做过反向解析，以下是sina的退信。

This is the mail system at host mail.cynovo.com.cn.

I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can delete your own text from the attached returned message.

    rejected. (in reply to RCPT TO command)

查看maillog时候，maillog日志显示status=bounced。。

请各位大侠赐教。。

我安装了LADP，在iredadmin里只能新建用户没有新建组，请教一下怎么新建组？谢谢

求LADP使用文档。。先谢谢各位大侠了。
