    Hi, After i finished setting up my SMTP server following this course , I configure DKIM records in my DNS zone, and I tested it with MXTOOLBOX

    but when I test my emails with mail-tester or send an email, it shows a not authenticated, which means DKIM is not working properly. How to Solve this?

    Dkim works by authenticating emails using private-public key authentication, private key on the SMTP server, and the public key in the DNS zone.  So this may happen if the dkim signing is not working from your SMTP server.

    To fix this in webmin, Open Putty and connect to your machine, then run the following commands:

    /lib/opendkim/opendkim.service.generate

    systemctl daemon-reload

    service opendkim restart

    for more info about what and how DKIM works, watch the attached video:
