我注意到，如果我键入服务postfix状态 ，则会出现错误：
Jul 01 17:39:01 mail postfix/cleanup[13921]: warning: connect to Milter service inet:127.0.0.1:8891: Connection refused 但这是什么意思，我该如何解决？ 这与DKIM有关？ 因为我试图设置它，它仍然无法正常工作。 哪些文件需要帮助？ 这里是我的opendkim.conf：
## CONFIGURATION OPTIONS # Specifies the path to the process ID file. PidFile /var/run/opendkim/opendkim.pid # Selects operating modes. Valid modes are s (signer) and v (verifier). Default is v. Mode sv # Log activity to the system log. Syslog yes # Log additional entries indicating successful signing or verification of messages. SyslogSuccess yes # If logging is enabled, include detailed logging about why or why not a message was # signed or verified.

感谢帮助！
OpenDKIM是一个不同的服务。 看看它是否运行。 你可以试试
sudo service opendkim restart
看看是否会导致错误。
鉴于你有Socket inet:[email protected]和Postfix试图连接到端口8891 ，configuration似乎没问题。 您可以使用netstat -l或lsof -i来检查OpenDKIM实际上是否正在侦听端口8891 。
