I use my own domain to redirect my netlify page to this domain:
This works well. However, I cannot forward some mails (from gmx.de) anymore, I get this error message:
550-Requested action not taken: mailbox unavailable
550 invalid DNS MX or A/AAAA resource record
But I cannot add A or AAAA records next to NETLIFY records.
How can I overcome this issue?
