as an example, rather than the existing

$ host -t txt _dmarc.cqx.ltd.uk
_dmarc.cqx.ltd.uk descriptive text "v=DMARC1\;p=none\;rua=mailto:3142 at dm.barwen.ch\;ruf=mailto:3142 at dm.barwen.ch\;ri=86400"

instead I configure

_dmarc.cqx.ltd.uk CNAME customer-1-arbitrary-foo.scanmailx.com

and you configure

customer-1-arbitrary-foo.scanmailx.com TXT v=DMARC1\;p=none\;rua=mailto:3142 at dm.barwen.ch\;ruf=mailto:3142 at dm.barwen.ch\;ri=86400

Now you can change that TXT record as you please, with no action on my part.
