I've just set up OpenDKIM on my CentOS 6 server but keep getting the following warning each time I start the service:

Cannot determine host's domain name, so skipping default key generation.

I have my server's hostname and domain name set up in /etc/sysconfig/network as well as in /etc/hosts but yet it seems that OpenDKIM fails to pick up that info.

Any ideas how I can fix this?

  • I can't recall as we switched over to a Windows server, but try removing localhosts from both of the files mentioned above - it might help.

Check you /etc/hosts, must like this:

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

93.170.131.123 myhost.com

After setting you /etc/hosts a restart is required.
