123 Reg has updated our mailboxes to their new platform and sent over the details to update our MX records on Cloudflare to point to their new server.
When I try to set up the first MX record they sent over:
DNS Entry: @
Name (required): @
Mail server (required): smtp.secureserver.net
TTL: 1 hr
In Cloudflare, I get the error: DNS Validation Error (Code: 1004) Change the content of your MX record to be a hostname (and not an IP address).
I don’t understand this as I haven’t put in an IP address.
For anyone with the same problem, the issue was that the email from 123-reg had ‘zero-width non joiner’ characters in the destination/target. The solution was to type out the domain rather than copy and paste it from their email.
