This tool generates the values for the DNS records. Sometimes this is needed if a customer controles his own domain name, and we need to supply the required records to the customer to make it work.

The SPF record is needed to get email working with AWS. sometimes a customer already haves a SPF record. In that case, it needs to be combined. This is the responsibility of the customer himself.
For domains in Open Provider this tool is probably never needed. Because the default dns template already contains most of the records on registering a new domain, and the DKIM records are generated automatically on launching a website.
For domains in AWS route 53, some of these records might be needed. But the DKIM and validation related records sometimes are filled in automatically with a click on a button in the AWS console.

Copy the table with all the records to an email, decide whether all the records are relevant, eventually discuss the records with Jan if in doubt. Because it is unwanted to ask the cusomer every week for adding one more record, it is better to have the customer set all the records all at once. Send the mail with definitive records in an email to Jan, so he can forward it to a customer.
