  • Exchange2013中断POP3和IMAP4的解决办法

    Exchange2013中断POP3和IMAP4的解决办法

    Exchange服务器意外重启。之后用户发现无法通过POP3和IMAP4收邮件,连接后会提示ssl error5。 但是Exchange模式可以用。

    去服务器上检查,相应的pop3和imap服务均已启动。

    端口是正常的,配置文件也没有变化。

    在服务器上用foxmail测试。地址填写127.0.0.1时却正常。

    【解决办法】

    检查服务器组件: 发现有2个组件处于inactive。

    9

    使用以下命令激活组件

     Set-ServerComponentState -Identity xxmail1 -Component PopProxy  -Requester HealthAPI -State Active

     Set-ServerComponentState -Identity xxmail1 -Component ImapProxy -Requester HealthAPI -State Active

    使用Get-ServerComponentState -Identity ex01 再次查看一下,是否全部为激活状态。

    QQ截图20160505150509

    最后问题解决。

  • sendmail 文件 virtusertable 管理虚拟域

    如同Apache一样,sendmail也允许使用虚拟主机功能,这是通过FEATURE(virtusertable)功能实现的,而虚拟主机的文件缺省是/etc/mail/virtusertable。这个文件的形式类似于aliases文件,即:左地址 右地址 ,中间用Tab键分开。还需要注意的是,虚拟域(左地址的域名),应该属于本机接收之列。

  • Sendmail邮件队列的管理

    1、队列文件通常存放在/var/spool/mqueue下面,每个待发送的邮件由几个文件构成,例如,我们可以看到下面的目录文件列表:

    [root@mail mqueue]# ls

    dfRAA27175 xfAAA00733 xfBAA00819 xfEAA32763 xfXAA00706

    qfRAA27175 xfAAA00784 xfDAA01360 xfFAA01616

    文件名字总是由一个两字符的前缀加上一个随机数字。前缀有四种: (更多…)
