Project: Create mta-sts.txt and subdomain on GitHub Pages - Template Repo

A GitHub template repository setup to quickly deploy an mta-sts.txt file into a .well-known/mta-sts.txt path on a mta-sts.domain.tld subdomain.

• Simply copy the template repo.
• Change the CNAME.txt file contents to mta-sts.yourdomain.tld
• Rename CNAME.txt to just CNAME1
• Change the .well-known/mta-sts.txt file to match your email MX records and version2
• Set up the DNS records to point to GitHub’s IP ranges.
  • 185.199.108.153
  • 185.199.109.153
  • 185.199.110.153
  • 185.199.111.153
• Publish to GitHub Pages - using the deploy from branch fine, no actions needed.

Default mta-sts config is for Apple’s MX records - change these to your provider.
