I have some troubles configuring SPF/DKIM for a VPS with a running instance of Postfix. Thanks to DMARC reports I'm finding and fixing always more issues.
Today I have a problem by setting SPF records in GoDaddy for a subdomain that matches the machine's name.
Given that domain is mydomain.com
and the host with mailserver is host.mydomain.com
.
On my GoDaddy DNS panel, host.mydomain.com
is a CNAME to somehostname.cloudapp.net
.
When I try to add a SPF record for the subdomain @host.mydomain.com
I get an error that there is already a host
CNAME record and I can't create a host
TXT record. The @
record for mydomain.com
is up and running, and all DMARC reports are fine with that.
The question is: how can I tell GoDaddy to create a host.mydomain.com
TXT record on DNS?
