Verify the authenticity of a received message

Enter the contents of the Message-ID header:

Enter in full shape, including angle brackets <>.

You can find the Message-ID when viewing the original contents of the received message. The name of the order differs in individual mail clients, in principle look for the item Show original or Message headers in the menu. If you are unsure, search Google for the phrase 'display email message headers'.

Identifiers are valid for 45 days, after which time it is no longer possible to verify the authenticity of the message. Only ad campaign message identifiers are in the database. You can verify a maximum of 3 identifiers in one hour.
