How to spot a spoofed E-mail?
A spoofed E-mail is a message that purports to be from a sender or a domain other than its actual origin.
One of the most direct ways to recognize a spoofed pattern is to send a spoofed E-mail to yourself, adjust its properties, re-send, and observe a changed result in your own mailbox. Use our free forensic mailer for fine-grained control, or use this page to author a basic message with an arbitrary "From" field.
How do you spot a spoof?
1) Paste an E-mail header here to analyze a particular message. The highlighted attributes will provide ample detail on message apparent origin, authentication checks, and other attributes.
2) Review the E-mail header. The header will contain message properties, including the sender's IP address and the results of E-mail security checks performed by your E-mail provider when the message is received. Use our Quick Header Codes to check what the header fields and codes actually mean.
3) Send yourself a spoofed test E-mail to see firsthand how spoofing works. You can specify your own sender's name and E-mail address or leave it blank. Will your SPAM solution catch the spoof? What will you see in the E-mail Header as the recipient?
4) Use the Forensic Mailer feature on this web site for granular control over various E-mail Header and Envelope fields. E.g. replay a past E-mail attack that your company experienced under controlled circumstances.
