@ac1d, we’re still working on a few details related to this behavior as this was an “interesting” issue. We don’t believe there was any change on the Netlify side regarding the API calls making the DNS zones but clearly the SOA records themselves did begin including an email address when previously they did not.
We haven’t followed up here yet because there are still some loose end. That being said, newly created DNS zones will no longer include the email address in the SOA record.
Because we didn’t make any changes on our side, one of the loose ends is tracking down which DNS zones are affected and which are not.
That being said, if in the meantime you (or anyone else for that matter) needs an SOA record updated, please let us know which domain is affected and we be happy to manually update those SOA records to get them corrected.
@ac1d, I enabled private messages (PMs) for your community user account if you don’t want to send the domain name publicly. If you PM us with the domain or domains, we’ll get them corrected.
