我在 ubuntu 20.04 上用 postfix 配置 dkim 大约花了 2 个小时。我尝试了所有方法,但 dkim 不起作用。

答案1
我遇到了同样的问题。我的声誉不够高,无法发表评论,因此留下评论并不能真正回答问题,但可能会帮助找到更好的答案。希望如此。
创建文件有助于 opendkim 启动。touch /run/opendkim/opendkim.pid
然后我发现你必须更改我刚刚对整个文件夹执行的文件的所有权。chown -R opendkim /run/opedkim
我相信问题始于该文件随后将所有权改回根目录,并且下次启动该过程时我收到同样的错误。
systemd[1]: opendkim.service: 启动后无法打开 PID 文件 /run/opendkim.pid (还不能打开吗?): 操作不允许
因此,这主要看起来像是所有权问题,而在此之前是文件不存在的问题。
我仍在调查,似乎仍存在一个问题,即套接字 local:/var/spool/postfix/opendkim/opendkim.sock 未创建,然后 postfix 发出抱怨,尽管 opendkim 正在运行。因此,我正在处理一个双层问题,但我想补充一下我的观察。
哦,我用的是 Debian
经过进一步调查并阅读上述评论后,我也确信这不是一个可以忽略的错误。
答案2
您正在 chroot 中运行您的 postfix:
SOCKET="local:/var/spool/postfix/opendkim/opendkim.sock"
但 systemd 正在尝试检查
/run/opendkim/opendkim.pid
答案3
根据Ask Ubuntu 上的这个答案,OpenDKIM 的 PID 文件可能不是必需的。该PidFile
行可能会引起问题,可以删除。
尝试注释该PidFile
行。
opendkim.conf:
#PidFile /var/run/opendkim/opendkim.pid
然后重新启动并检查状态。
这是一种方法。当然,还有很多其他因素,取决于你需要完成什么。
