你的邮件收发量是否很大？单位时间（例如一小时、或30分钟，等）内大概收发多少邮件？
不知道是否因为收发邮件较多导致 cluebringer 处理不过来出错。但之前没有听说过因为收发量大导致 cluebringer 出现这样的情况，而且 cluebringer 开发者声称 cluebringer 的性能非常好，在 ISP 环境完全没问题。
我这邮件量是比较大，单位时间的邮件量我不知道怎么统计。

只有这条日志看起来比较可疑，但又无法确认到底什么问题。建议先检查一下这个文件的权限。
权限如下：
-rw-r--r-- 1 cluebringer cluebringer 5 Dec 26 15:54 cbpolicyd.pid
我不做任何操作的情况下，虽然有部分邮件报错，但是很多邮件还是能够正常收发的。
今天在出现故障时有以下信息：

guo_xianglin 写道:ZhangHuangbin 写道:提示是连接到 cluebringer 服务超时了。那这时候 cluebringer 的日志里有没有提示自身是否运行出错？以及错误的原因？
我看了日志没有发现异常，还可能有其他的原因吗？之前一直运行正常，最近才开始有这个问题，最近没有修改过配置。
我仔细看过日志了，办错时时间点cluebringer没有日志，maillog的日志信息如下：

ZhangHuangbin 写道:提示是连接到 cluebringer 服务超时了。那这时候 cluebringer 的日志里有没有提示自身是否运行出错？以及错误的原因？
我看了日志没有发现异常，还可能有其他的原因吗？之前一直运行正常，最近才开始有这个问题，最近没有修改过配置。
我仔细看过日志了，办错时时间点cluebringer没有日志，maillog的日志信息如下：

此错误最近才开始出现，并且越来越频繁，请求支持，谢谢！

我在张工之前回复的帖子中看到过类似问题，可以通过mailbox的一些字段进行控制， allowedsenders 、 allowedrecipients、rejectedsenders 和 rejectedrecipients。
- 拒收所有发件人发给 user@example.com 的邮件（rejectedsenders='@.'）
- 允许 user@example.com 接收来自 example.com 的邮件（allowedsenders='@example.com'）
- 禁止 user@example.com 发邮件给任何人（rejectedrecipients='@.'）
- 允许 user@example.com 发送给 example.com 的邮件（allowedrecipients='@example.com'）
注意：
- 这里表示“所有人”的用 '@.' （一个 @ 符号加一个英文句点）表示。
- iRedAPD 会优先处理 allowedsenders 和 allowedrecipients，再处理 rejectedsenders 和 rejectedrecipients。

由于服务器硬件故障，在备份服务器运行，出现在部分foxmail用户无法收取邮件，outlook用户不受影响，foxmail用户可以通过 工具--远程邮箱管理 看到邮件（很多人显示邮件不全），状态为“不处理”，部分用户手动执行收取邮件可以收取。
张工，你好！我想请问一下除了spam/virus 扫描会使邮件队列比较大以外还有哪些设置或者参数可能也会影响邮件收发效率啊，谢谢！
我有两台邮件系统邮件队列经常特别大，用户都在1000人以上，一个版本是0.8.0，另一个是0.8.1，服务器都是IBM 3650M3服务器，双CPU，16G内存的，以前按照下面的方法修改后，效果比较明显，当现在0.8.0还是经常出现邮件队列超过300以上的情况，投递时间比较长，出现超过40分钟邮件还在队列中，0.8.1相对没这么严重。谢谢。
$policy_bank{'MYUSERS'} = {
...
# don't perform spam/virus/header check.
bypass_spam_checks_maps => [1],
bypass_virus_checks_maps => [1],
bypass_header_checks_maps => [1],
# allow sending any file names and types
bypass_banned_checks_maps => [1],

我想请问一下iredmail默认配置有没有对最大收件人做限制，我现在有用户一封邮件暗送给1200个邮件地址时无法发送，需要分多次才能发送，并且发送后收到大量退信退信内容很多都是time out和refused connection
谢谢！
对方使用新浪邮箱发送给xxx@xx.com地址时收到退信，不知道是什么原因，请告知，谢谢！
我是用的是iredmail-0.4.0，最近同事总是遇到这种问题，遇到次数较多，有时对方重发就能收到了。
多谢大家了！
以下是退信内容：
主题： 系统退信
尊敬的用户，
我们很遗憾的通知您，您发的邮件中有一个或多个接收人没有投递成功。

张大哥，我试了下修改文件/etc/postfix/main.cf
mydestination = $myhostname, localhost, localhost.localdomain, localhost.$myhostname,test2.com
这样test1发送邮件给test2的时候，客户端就会直接提示用户不存在的错误了，可以起到提醒的作用了。
张大哥，现在我不想升级现有邮件系统，能做到吗？
考虑到升级太麻烦，跳跃的版本太多了，存在一定风险。
由于公司使用内外两套邮件系统，两套系统之间不能通信，怎么设置可以禁止xxx@test1.com发送给xxx@test2.com 如果发送，系统直接退信。xxx@test1.com可以发送给出xxx@test2.com以外的邮件地址。
我现在使用的是iredmail-0.4.0 由于运行稳定，没做升级。
谢谢！
公司邮件往来比较多，再加上服务器出现故障后不容易马上发现，如果不是有双机热备的话出现问题后影响比较大。
我是用的mysql存储用户信息：由于alias信息比较多，每次有员工离职后，都需要需要手动从alias表中查询用户存在于那些别名列表中，然后挨个删除，这样操作比较繁琐，浪费时间，希望能一次性再删除用户的同时删除alias表中的相关信息。
谢谢！
1，我想请问一下，我现在用的是iredail-0.4.0怎么可以实现双机热备啊。
2，每次维护账号的时候需要手动删除alias里面的信息，能不能做到直接在删除账号时从alias中也将用户信息删除。
谢谢！
这个问题我也遇到了，上次张大哥说是ssh终端问题，建议你用putty试试。
我之前邮件系统使用的是iredmail-0.4.0 账号数量已经超过了1000个，现在想重新安装一台服务器替换以前的旧服务器，在新服务器上安装iredmail-0.6.1后想要恢复以前的账号信息，需要做些什么操作？
请高手帮忙，谢谢！
