I have a domain name through namecheap.
Proxied through cloudflare.
I recently purchased an email through namecheap as well. But every time I try to email myself from gmail or outlook, I get failure responses.
“The response from the server was 554 5.1.1 recipient address rejected: undeliverable address: host mail-outgoing.relay-fef.svc.cluster.local[10.27.8.67] said: 554 5.7.1 relay access denied in reply to RCPT TO command”
I followed the guide here
Add 2 mx records, a srv record, a txt record and 3 cnames.
Everything looks fine to me…
