Hi All. Hopefully my terminology is correct and I make sense.
We have a main domain "something.com.au" with a few sub-domains, "this",
"that", etc.
For all of our 'A' records in something.com.au, we have specified TXT
records for SPF, however our sub-domains contain CNAMEs only.
It appears TXT and CNAME records for the same string/host cannot co-exist.
We are able to specify an SPF record for the origin only in each sub-domain.
Open to any suggestions on how to get around this issue.
Thanks in advance.
