Paste a suspicious email's headers. See who actually sent it, the route it took, and whether it passed the checks mail servers use to catch fakes.
What we keep: the address that received the email, the sender's address, and the result -- so Sonny can follow up on scam attempts aimed at your business. Never the headers, the message, or anything in it. No links are visited and nothing from the email is sent anywhere. Privacy policy
Sonny can check whether your own domain can be faked like this, and lock it down so scammers can't send as you.
