Migrate to managed MTA-STS #2
Description
Cloud has introduced managed MTA-STA.
The described setup is suboptimal, as it uses a worker for the target endpoint. Better solution would be to point https://mta-sts.markavenue.sk/ to https://mta-sts.mx.cloudflare.net/ and change Host header using Origin Rules. However, this feature is currently available to Enterprise plans only.
Cloudflare says that setup simplification is being worked on, so lets wait for further development.
