recently set up mailcow dockerized on (not my actual domain) mail.example.com, and added example.com as a domain in mailcow and created some mailboxes such as email@example.com firstname.lastname@example.org etc.
Using dmarcian.com to check, I get all green for domain example.com, but subdomain mail.example.com shows 2 green and missing DKIM record. Obviously can’t add the host as a domain in mailcow so how would I get a dkim key for it? Or is the warning for subdomain safe to ignore?
Any insights welcome, thanks!
