Subdomain for email providers

On email providers github page I found
Please note that in any email provider, you must verify and use the subdomain, e.g. . If you verify the domain only, e.g. , mail will not be configured correctly.
It is not quite clear. Should I obey this rule if my discourse works on, not on

You are correct, if you have installed at the apex domain (which I do not recommend) then you should validate email at the apex domain.
