CNAME records not propagating

Integration in devices/software
#1

Hi,
Not an expert in DNS so I’m sure I’ve done something wrong. I’ve set a bunch of MX, A and TXT records for my custom domain, which have all propagated fine, however the CNAME record that I set at the same time is not showing up anywhere, and it has been near enough 48 hours at this point.
The record is as follows:
name: ‘sig1._domainkey.burl.es’
data: ‘sig1.dkim.burl.es.at.icloudmailadmin.com.’

I have made a similar change to one of the free dns.army domains dynv6 provide, and the records are also not propagating on that URL.

Anyone have any idea why this isn’t working?
Thanks

The underline _ ist not allowed in DNS. Try a minus - instead.

and its seems to work now:
;; ANSWER SECTION:
sig1._domainkey.burl.es. 300 IN CNAME sig1.dkim.burl.es.at.icloudmailadmin.com.

Sorry, I confused hostnames and domainnames.

Good to hear that it works now,
