Hello, trying to fix the mailjet MX DNS record but with no success.
this r my DNS screenshot where the red draw is my IP address and blue my domain name
I’ve never seen a _domainkey use an “A” record. Your domain uses a TXT record farther down the list.
You’ll have to ask Mailjet for clarification. Cloudflare will publish whatever DNS record you enter, so just make sure it’s correct. And set to DNS Only any time it’s a mail-related DNS entry.
