My server is running Ubuntu 18 and I installed a fresh virtualmin on it. I then went on to enable DKIM but there was an error during installation. i fixed those and installed opendkim manually through SSH. Then I enabled outgoing signing and it worked fine. The problem is outgoing mails are not being signed with DKIM. In the /var/log/mail.log I have several lines of
warning: connect to Milter service inet:localhost:8891: Connection refused
I've searched for this error and there are many posts out there but for me they either didn't work or I couldn't understand them. Could someone help me figure out what the issue is here and how can we fix this?
