So I had this email back and forth with support about this, but it really left me confused. I think he did not understand me. I have a website on a subdomain. Lets for example sake say I have the website "manatees.nature.com" to show all the awesome manatee shots in nature magazine. I want to host this website at smugmug, because, why not, and where else, right?
But, i also want my readers to send email to [email protected] The moment I add "manatees.nature.com" as a custom domain, it seems to insist on it being a CNAME to domains.smugmug.com (instead of A records, which would work just fine). But that means I could never have email on [email protected] because you cant mix CNAME and MX records.
Surely this must be an oversight?
(ps, the real domain is https://underwa.ter.net, but I think it seems to confuse people).
