Postfix 无法启动,但 dovecot 正常

Postfix 无法启动,但 dovecot 正常

我的 postfix 服务无法启动。这是消息:

Job for postfix.service failed. See 'systemctl status postfix.service' and 'journalctl -xn' for details.

这是服务状态:

postfix.service - Postfix Mail Transport Agent
  Loaded: loaded (/usr/lib/systemd/system/postfix.service; enabled)

请帮我解决这个问题,我不知道如何解决。非常感谢。

我遇到了同样的问题,使用从以前的机器导入的配置。

这是我解决这个问题的方法:

$ sudo rm -v /var/lib/postfix/master.lock
$ sudo systemctl start postfix

就我而言,之前的尝试中还存在后缀进程留下的问题,解决方案如下:

-- 检查 postfix 是否未运行:

$ ps faxu | grep -i [p]ostfix
root     12854  0.0  0.2  92004  2236 ?        Ss   07:23   0:00 /usr/libexec/postfix/master -w
postfix  12855  0.0  0.4  98320  4088 ?        S    07:23   0:00  \_ pickup -l -t fifo -u
postfix  12856  0.0  0.4  98388  4128 ?        S    07:23   0:00  \_ qmgr -l -t fifo -u
postfix  12872  0.0  0.4  98332  4672 ?        S    07:29   0:00  \_ tlsmgr -l -t unix -u

-- 如果您有 postfix 进程正在运行,请将它们全部杀死:

$ sudo kill -9 12854 12855 12856 12872

-- 杀死所有进程后,删除 master.lock 文件并使用 systemctl 启动 postfix (见上文)。

最后,不要忘记queue_directory应该指向/var/spool/postfix ...
