I have a main site blaze-in-saddle.com. It works perfectly.
When I bought this domain name, I also bought blaze-in-saddles.com (note the added S), just to catch misspellings. It is listed in the Netlify DNS settings as a domain alias It works perfectly, too, except for one thing.
I am trying to assign a MX host for blaze-in-saddles.com (the domain alias) separate from that of the primary domain name, but I can’t see how to do this. Creating a new mail subdomain refers only to the primary domain.
Should I move the DNS for the custom domain alias from Netlify, or can I do this within the Netlify DNS panel?
