[操作系统]postfix与sendmail冲突


在Linux服务器(CentOS release 6.6)上配置好了sendmail后,测试发送邮件时发现有问题,检查sendmail服务的状态,发现其处于“sendmail dead but subsys locked”, 检查发现postfix服务也在运行。只需要将postfix服务停掉即可。为什么会出现这种情况呢?Something was occasionally causing the postfix service to start which then caused the status of sendmail to jump to dead but subsys locked. 两种似乎不兼容。

操作步骤:

1:检查sendmail服务的状态

[root@DB-Server ~]# service sendmail status
sendmail dead but subsys locked
sm-client (pid  22112) is running...


 

2:检查postfix服务的状态

[root@DB-Server ~]# service postfix status
master (pid  1777) is running...


 

3:停止postfix服务

[root@DB-Server ~]# service postfix stop
Shutting down postfix: [  OK  ]


 

4:重新启动sendmail服务

[root@DB-Server ~]# service sendmail stop
Shutting down sm-client: [  OK  ]
Shutting down sendmail: [FAILED]
[root@DB-Server ~]# service sendmail stop
[root@DB-Server ~]# service sendmail start
Starting sendmail: [  OK  ]
Starting sm-client: [  OK  ]



5:禁用postfix在reboot后自动启动

      检查一下是否有设定 postfix 在 reboot 后自动启动
chkconfig --list | grep postfix

chkconfig postfix off
