Web Hosting Service (For MTA-STS with own domain)

Open mullbird opened this issue 7 months ago • 3 comments

Is it possible for you to provide a simple web hosting service just for hosting mta-sts.txt?

JFYI you can use cloudflare workers free tier or github pages to host mta-sta

Hmm, is that really a good option? MTA-STS uses HTTP, but it's not something viewed by web browsers—it's read by machines. The response must be a text file, and it's problematic if a CAPTCHA appears based on the IP address. Can Cloudflare handle this?

GitHub Pages isn't a good option because it doesn't support IPv6.

IDK but when you set up cloudflare email routing they suggest using workers for mta-sts: https://developers.cloudflare.com/email-routing/setup/mta-sts/

I suppose that should work fine. Was using it myself earlier with cloudflare email routing and still use it with purelymail.
