How it works

Email Health Pro is a real mail server you can send to. It accepts every message at port 25, then grades it as it arrives — without rejecting anything.

1. 1.

   Accept on port 25

   Your sending server connects to emailhealthpro.com over standard SMTP — exactly the same path it would take to Gmail or Outlook. We accept STARTTLS, log the negotiated cipher, and capture the EHLO, MAIL FROM, RCPT TO, and reverse-DNS state of your sending IP.

2. 2.

   Run authentication checks

   SPF, DKIM, DMARC, and FCrDNS run inline. Each check writes its result into custom X-Mailcheck-* headers so the result is visible in the raw message and stored alongside it.

3. 3.

   Grade the content

   SpamAssassin runs across the body and headers, producing a score and a list of rules that fired. We additionally check header alignment (From / Return-Path / List-Unsubscribe / Message-ID), MIME structure, attachment types, and total size.

4. 4.

   Reports re-score against the latest rules

   Reports render the first time you look them up. That way, when we tighten a grading rule, your old test message gets re-scored against the new logic automatically — no need to send again.

5. 5.

   Anonymous lookup

   You retrieve your report with your From address plus a short token we include in the test address. No account, no email collection, no login.
