For A entries, in most cases, with most providers, you only need to specify mail and not the FQDN, or fully qualified domain name.
So instead of:
A mail.yourdomain.com IP_ADDRESS
… you’d want to use:
A mail IP_ADDRESS
This is the case with DigitalOcean’s DNS, as well as most domain registrars. Your domain is appended by default, so there’s no need to add it with the entry.
