Today I use DigitalOcean as hosting my software.
Our platform is a SaaS that sends emails from wildcard domains, example: firstname.lastname@example.org; email@example.com;
Email services like Gmail, Outlook, etc, require SPF Records for subdomains, to avoid spoofing problems. The problem is that DigitalOcean does not allow a wildcard TXT record (*.example.com), and creating a subdomain for each account is not viable, as there are thousands of subdomains.
Is there a way to create a DNS record that can work around DigitalOcean's limitation?
There are more than thousands of subdomains used to send email, and it is impossible to create one by one. And also update all in batch.
