Twissell I think the "fallback emailer" is literally just searching for a "mail" executable on the machine.

It's pretty outdated now, since emailing directly from your machine is a good way to just get your emails to land in a spam bin somewhere. We should probably just update this to ℹ️ or ⚠️ instead of an error.

IMHO, that's the right solution.

Everything works fine, you just need setup following list of records

  1. Reverse DNS for VPS
  2. SPF for domain specified
  3. DKIM and DMARC as well
  4. MX record.
