I've scowered the forums and failed to find any additional information as to what might be preventing postfix from signing my messages for DKIM.
I followed the guide to install virtualmins dkim feature. I dropped the key down to 1024 instead of 2048 per suggestions in the forums.
I've waited a reasonable amount of time for DNS to propagate.
DNS is propagating. I've checked several of my hosted domains and they all have the appropriate record.
Sending test messages I am getting a reply from the email@example.com that the message is just not signed (Neutral)
Am I missing a toggle in the settings somewhere?
Main.cf has smtpd_milters = inet:localhost:8891 non_smtpd_milters = inet:localhost:8891
But some of the reading I've done suggest that this needs to be smtpd_milters = local:/opendkim/opendkim.sock non_smtpd_milters = local:/opendkim/opendkim.sock
I did try changing that but the message comes back again as not signed.
