Authentication results
SPF passed for example.com.
DKIM passed using example.com / selector selector1 (rsa-sha256).
DMARC passed for example.com with policy quarantine and the message is aligned.
No ARC headers were found in this message.

About This Live Email Authentication Test
Mailvovo receives a real email at a generated test address and analyzes the complete message headers to verify SPF, DKIM, DMARC, ARC, sender alignment, routing, and delivery evidence. This provides message-level authentication evidence instead of DNS configuration alone.
What it checks
- SPF, DKIM, DMARC, and ARC results
- Sender alignment (Header From, Return-Path, DKIM d=)
- Complete email headers and routing path
- Delivery and Received chain analysis
- Authentication findings and recommendations
- Actual message-level evidence
Who it’s for
- Domain owners
- IT administrators
- Email deliverability teams
- Security analysts
- Marketers and product teams
- Agencies and MSPs
Important to know
- Send a real email from your own provider
- Results depend on the actual message received
- Some senders do not include ARC headers
- Test addresses expire after a limited period
- This is not a bulk-delivery testing tool
- A pass does not guarantee inbox placement

Frequently Asked Questions
Generate a temporary Mailvovo test address, then send a real email to that address from the provider or system you want to test.
Mailvovo reviews message-level SPF, DKIM, DMARC, ARC, sender identity alignment, routing evidence, and important email header fields.
The initial design uses temporary addresses intended for short diagnostic sessions. The exact expiry period is shown when a live test address is generated.
ARC is commonly added by forwarding or intermediary systems. Many direct-delivery messages legitimately contain no ARC chain.
Each test session is intended to analyze one message clearly. Generate another test address when you want to run a separate test.
Use the findings to identify whether the problem is SPF, DKIM, DMARC, alignment, or routing related, then use the matching Mailvovo DNS checker for deeper configuration analysis.
