MTA-STS.st-johnsschool.net

HUGE THANKS TO JIMEH FOR THE TEMPLATE: [https://github.com/jimeh/mta-sts-on-github-pages/tree/main]

Template repository for hosting mta-sts.YOURDOMAIN/.well-known/mta-sts.txt on GitHub Pages.

This serves as alternative supplier option in step 3 described here: [https://www.security.gov.uk/policy-and-guidance/set-up-tls-rpt-and-mta-sts/]

Usage

• Add a CNAME DNS record at mta-sts.YOURDOMAIN pointing to GITHUB_USER.github.io.
• Add a TXT DNS record at _mta-sts.YOURDOMAIN indicating the use of MTA-STS, and update the id value on policy change.
• Create a new repository from this template repository.
• Replace YOURDOMAIN with your custom domain in CNAME.
• Update .well-known/mta-sts.txt to set mx directives to match the MX DNS records of your domain.
• Turn on GitHub Pages (Settings > Pages) for the repository, using the root (/) of the main branch as source.
• Turn on Enforce HTTPS setting for GitHub Pages.
  • Please note that if GitHub tells you to get ssl for your custom domain, try removing your custom domain from the field and then re-adding.
  • After typing and saving it again, DNS should be succesful and you should be able to tick “enforce HTTPS”.
