🪩 What is this place?

This tiny corner of the web exists so that mail from @yamada.io has a real, resolvable home. Think of it as a tasteful 2003 time capsule that happens to be HTML5-valid, responsive, and polite to spam filters. Yes, sweetheart, it’s minimal on purpose.

🔐 Why it helps

Many providers weigh domain presence, HTTPS, and consistent DNS (A/AAAA, MX, TXT) when deciding whether to trust email. A simple, legitimate website plus proper SPF/DKIM/DMARC signals “this domain is real”.

🧭 Best practices

  • Serve over HTTPS with HSTS.
  • Publish A/AAAA, MX, and TXT (SPF, DKIM, DMARC) records.
  • Use a real postmaster@ and abuse@ if possible.
  • Keep WHOIS privacy sane and consistent.

📫 Email authenticity at a glance

If you received an email claiming to be from @yamada.io, you can verify it by checking these headers with your mail client:

  1. SPF: “pass” for the sending IP/host.
  2. DKIM: “pass” with a yamada.io selector.
  3. DMARC: policy aligned and not failing.

If any of that sounds like alphabet soup, relax—just know this site exists so your inbox knows we’re legit.

Under construction… like it’s 1999 (but with content security policies).
