Using same subdomain for email and page

[Matt Madzia]

I am attempting to do the following:

1. set up custom DNS for our status page, attempting to use https://status.mydomain.com
2. set up custom email for the same domain, noreply@status.mydomain.com

I am able to set up a CNAME for status.mydomain.com, and I was able to set up the email DKIM and CNAMEs.

However, it is requiring a TXT record for domain ownership and SPF. AFAIK you can't have a TXT record and CNAME record with the same hostname. My DNS provider is not allowing me to add a TXT record with the same hostname as well. Is having DKIM enough for custom emails, or am I forced to use different subdomains for email and the page?

G'day Matt!
I'm Scot, from the Statuspage Support team in the APAC region.

You're absolutely right you can't put a TXT record on a CNAME record - RFC 1034 doesn't allow this! Fortunately you can apply it to the APEX domain record as per our Statuspage documentation on configure-your-dns, 

If your domain is a subdomain the record can be placed on the subdomain itself or the apex domain. Both will be checked to complete verification for domain ownership.

So to setup the domain ownership - you need to add the TXT record to your mydomain.com DNS entry, and we'll reference that when doing the domain ownership check for you.

Kind Regards,
Scot.
