I need to set my MX records pointing to mailgun to subdomain.example.com for use with an email service provider. How can I do this via curl without making an actual subdomain? Somebody said here this is possible with the API, but he didn't say how.
If you're looking to create an MX record for the subdomain itself (vs pointing the MX to a subdomain like mail.yourdomain.com) you would need to use a different DNS service to delegate DNS for the subdomain. DigitalOcean's DNS doesn't currently support subdomain delegation but will allow you to create the record for the subdomain.
If you're just looking to create an MX record for your domain and point it to mailgun you can use the API to create the MX record itself. This section of the API documentation includes and example of the curl command to do this.
Ah yes! I actually figured that out and posted it as a comment in the place I linked to, but I forgot about this question. Thanks!
