Email Check
Paste a raw email and see how authentication headers look for deliverability.
What it’s for
Debug spam folder issues: verify SPF/DKIM/DMARC results as seen by receiving servers.
How it works
Paste the full source of a message (headers + body). We parse Authentication-Results / Received-SPF and optional List-Unsubscribe. If Rspamd is configured, we also score the message.
What you get
Friendly pass/fail for auth signals plus safe header excerpts (full mail is not stored long-term).
We look at
- SPF result
- DKIM result
- DMARC result
- List-Unsubscribe
How to use
- 1 Send a test to the address shown on the form (optional).
- 2 Copy “show original” / raw source from your mailbox.
- 3 Paste it here and review authentication findings.
