So, I followed this link to setup opendkim on my clearos server and generate a key. At one point it says to

Test your DNS record and signing: dig -t any YYYYMM._domainkey.mydomain.com

, to which I did. I get a response back saying,

communications error to 127.0.0.1#53: end of file

. I have no idea what that means. Everything else seemed to go OK, although I have to receive an email back after sending a test mail to check-auth@verifier.port25.com.

Do I need to include the dkim key in my Google Domain DNS settings as a TXT file?
