I am redoing an existing site, but after linking their domain to netlify their emailserver stopped working, i’ve been told to put an A record, an AAAA record, and a TXT record in the DNS, which supposedly is purely to make email work again.
Unfortunately I get the common problem of “dns_api damesdewit.nl - damesdewit.nl/AAAA: 400 - link exists, all config must be empty” (except for the TXT)
What should I do?
