Restricted CNAME Records
My C records are not working
We have restricted the use of the following CNAME records:
e
email
ftp
imap
mail
mobilemail
pda
pop
smtp
webmail
www
These CNAME records are restricted because they are commonly required by your hosting provider for essential applications like email. The www record, in particular, is restricted as it is best practice to specify the base domain for www—most registrars and hosting providers have already created this record by default.
We require the use of a subdomain to ensure that your application is built on the base domain. This also allows us to redirect referral links to your base domain once your page is live.
