sendmail,postfix是邮件服务器软件,用来传送邮件的。即MTA,RAK部落昨天在
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
RAK部落发现,按照这样来操作的话,基本就可以解决“postfix与sendmail对冲”的问题了,如果大家有更好的方法,在下方留言即可。
