I'm attempting to configure opendkim on my raspberry email server that has a dovecot/postfix setup already configured.

I have followed some tutorials and some forum posts to further diagnose my issue. Excerpt from my syslog:

Apr 16 08:55:06 raspberrypi postfix/smtpd[24384]: warning: connect to Milter service unix:/var/run/opendkim/opendkim.sock: No such file or directory

When I go to check if the file exists. It is not there. This leads me to believe that either my opendkim.conf file is either being ignored, or there is a permissions issue. However i have not been able to resolve this with my attempts.

Tutorial I Followed

Below is a question I referenced

unix:/var/run/opendkim/opendkim.sock: No such file or directory

I can't find the forum post that lead me to believe that this is an OS issue (Raspbian/Stretch), however there was one out there dated at SEP 2017

Another post I tried:

https://serverfault.com/questions/796742/connect-to-milter-service-unix-var-run-opendkim-opendkim-sock-no-such-file-or

EDIT 1:

The result of attempting to manually start the opendkim.service

Apr 18 15:49:29 raspberrypi systemd[1]: opendkim.service: Unit entered failed state.

  • Is the `opendkim` server process running? That creates the socket that postfix talks to. – Stephen Harris Apr 16 '19 at 23:51
  • It is not, it fails to start. Then returns the error from my syslog – Pants Apr 17 '19 at 14:05
  • The error you show is coming from postfix and is a consequence of opendkim not starting. You need to debug the opendkim process. – Stephen Harris Apr 17 '19 at 14:25
  • Are you saying there should be an error coming from opendkim instead? I'm attempting to debug why the .sock file is not being generated. – Pants Apr 18 '19 at 14:44
  • You need to manually start opendkim. Postfix will not automatically start it. – Stephen Harris Apr 18 '19 at 14:46
  • I have updated the question with the result of attempting to manually start the service. There is no clear cut answer for the reason for the failure, which is why i went to the syslog – Pants Apr 18 '19 at 14:49

I ended up solving my issues. There were a plethora of issues riddled throughout my /etc/default/opendkim.conf file. Mainly misspellings. (Result of following a tutorial, as I wasn't careful)

My main issue was that my opendkim service was not running. The service should still run even if your dkim is not signing your messages.

For those having similar issues, id like to recommend referring to ALL of your log files. Some issues may stem from parent issues, as well as some logs may give you a better idea for what the root problem is or even a better description.

See these below logs...

/var/log/syslog
/var/log/daemon.log
/var/log/mail.err
/var/log/mail.log

Some of these logs can be very length, so make sure you are looking at the newest entries, as well as testing your problem and verifying with a close timestamp.
