I activated email routing on my domain, but I can’t seem to get it working. All DNS options are in place, I have a catch-all forward, but I always get the following error message when sending an email:
<[email protected]>: 126.96.36.199 does not like recipient. Remote host said: 521 5.3.0 Upstream error Giving up on 188.8.131.52. STARTTLS proto=TLSv1.2; cipher=ECDHE-RSA-AES256-GCM-SHA384; subject=/C=US/ST=California/L=San Francisco/O=Cloudflare, Inc./CN=*.mx.cloudflare.net; issuer=/C=US/O=DigiCert Inc/CN=DigiCert TLS RSA SHA256 2020 CA1;
Is there a way to reach the CloudFlare email team so they can fix this? It seems like a bug.
