Let's say I've got a wildcard subdomain CNAME for root domain:
*.domain.com CNAME domain.com domain.com A 18.104.22.168
This works well for websites, e.g. subdomain.domain.com.
Now let's say I have an MX record on the root domain.
I assumed that emails to: firstname.lastname@example.org would work, but they fail. Emails of the form email@example.com work just fine.
Where am I going wrong?
