Have a facility that creates an SPF declaration automatically in user’s DNS

If your DNS is hosted by AA and you send mail using AA’s servers, in the clueless DNS setup it would be good to document the correct SPF TXT declaration for email sent using AA’s mail servers, either partly or entirely (with a warning about sending not always through AA mail servers). Or even have a feature to automatically add an SPF declaration, and check an existing one.

My previous mail service provider had a feature in their user-DNS setup UI with a button that added an SPF TXT record.

It would also be good if AA supported the use of an SPF include if needed.
