我的要求是,对指定域发来的邮件通通接收,对特定域发来的邮件,一律拒绝

如:  a.com                这个域名发来的所有邮件都接收,在服务器上应该修改哪个文件来设置?
        b.com                 对这个域发来的邮件,一律拒绝,在服务器上又应该怎么设置?

我今天在网上找了很久,也没找到详细一点的说明,才来发贴子寻求帮助

我提个建议:
      我觉得本论坛应该做个收索功能,也许很多问题已经回答解决过了,因为没有收索功能,而在反复的问与回答,这样很是浪费时间


非常感谢本论坛一直以来的支持,希望越做越好!

非常感谢,很有可能是我的解析有问题,后来把解析修改下了,就正常了,再次感谢ZhangHuangbin 的热心and及时的回复

我现在把这个不能收外域的域名绑定到另一台邮件服务器上去,日志如下:

但还是一样收不到外域发来的邮件

我这台机器一直运行是正常的,其它几个域名的邮件系统是正常的,就这一个不正常。我没有装sendmail,此台服务器就运行着LAMP,加iredmail0.5.1的

这是来于QQ邮箱的退信:
收件人邮件地址(support@flash-video-mx.com)不存在,邮件无法送达。

yahoo的退信:

现在日志文件里面都看不到相关退信邮件的记录

在同一套邮件系统中,存在着几个域名,其中一个域名拒绝所有外域发来的邮件


gmail发信,退信内容如下:

Technical details of permanent failure:

是不是在黑名单上自动拒绝了?我都不会设置黑名单

不做自动同步,收发邮件的时候与实际时间不相符,一般要比实际时间慢

提示好像是时间同步有问题,我现在同步的时候是中科院的时间服务器,还是一样,貌似时间比iredmail默认的时候快了,就会自动退出,慢了倒不会,一时找不到解决问题的办法,各位帮帮忙,在此谢谢了!

今天一上班发现了件很奇怪的事情,有几个以我们公司域名的邮箱向非公司邮件以外的邮件地址发邮件,内容都是些广告内容,有点像是别人盗用了公司邮箱在发垃圾邮件,但我到后台查了下,发垃圾邮件的邮箱并不在我们系统中存在,很是奇怪,不知道有没有人也遇到过类似的问题?

比如说:xxxx@moyea.com.cn  这是发垃圾邮件的邮箱,但这个地址在我们的系统中并不存在


我是在www@这个邮箱里面看到这些垃圾邮件的,这些垃圾邮件地址在向外发送邮件时,www这个邮箱也同时有收到

我查了一下午,最开始以为是公司内部有人在发,一个个排除都不行,暂时没办法了,大家帮帮忙

OK,解决

在重dovecot时,出现如下提示,不知道什么意思,是否对系统运行有影响

[root@mail ~]# service dovecot restart

                                                           [  OK  ]

这25W都是一天发的,是系统里面有一个程序在不停的发,导致我要的邮件没办法正常收看

我的www@moyea.org这个邮箱里面有25万多封邮件,现在提示已满
save failed to INBOX: Quota exceeded (mailbox for user is full)

请问,要怎么用命令清除这个邮箱里面的所有邮件?
因为通过B/S访问,根本登陆不进去,可能是因为邮件太多的原因

mail.moyea.org是我的主机名,这样查起来就麻烦了,文件太多,查起来要花不少时间

www@myea.org这个邮箱在狂收邮件,我查了下,有几十万封,都是些系统发来的邮件,要疯狂了
老大,要怎么解决呀?谢谢

问题已经解决,我也不知道问题出在哪里,折腾了几一在,最后把收不到邮件的域名删了,重新建过,一切正常了

同一个邮件系统绑定了两个域名,A域名可以正常收发邮件,B域名只能发送,不能接收
B域名的退信内容如下:
Delivery to the following recipient failed permanently:

    jony@moyea.com.cn

看起来好像moyea.com.cn这域名拒绝接收所有邮件

最近公司出于安全考虑,要给一部分人的邮件实行监控,只监控用户发送的邮件,接收的不监控

现在想到的办法有两个:(因为公司购买了个硬件设备,邮件是禁止发送附件的)
1.对指定的部分用户发送的邮件在服务器上自动转发一份到监控邮箱
2.关键字过滤,当包含指定的关键字时,绝对邮件的发送,并转发一份到监控邮箱


现在我的要求是,对部分用户的发送邮件系统能自动转发一份到监控邮箱,这是最理想的;如果这样实现起来比较困难或者说不稳定可以采用所有用户的发送邮件都自动转发到监控邮箱

谢谢各位的指教!
