Subject: Send $$$
From: "Assistant" <[email protected]>
To: [email protected]
Reply-To: [email protected]
Message-ID: <[email protected]>
- From: Displays the message sender. Spammers can easily fake sender addresses. See Email spoofing explained for guidance on detecting fraud email.
- Subject: The topic of the message as indicated by the sender.
- Date: The date and time when the email message was composed.
- To: Displays the addresses listed in the To: and CC: fields. Headers do not show any addresses that were included in the BCC: field, as these addresses were intended to remain private.
- Received: Displays a sequential list of computer and servers that received this message, the time they received this message, and the final destination of the message. Received appear many times in a message header and should be read from bottom to top, as the first recipient is at the bottom of the header.
- Reply-To: Determines which email address is auto-populated when you click the reply button to reply to an email in your email client. Spammers can easily fake reply-to addresses. See Email spoofing explained for guidance on detecting fraud email.
- Return-Path: Like the Reply-To: address, this is where return mail is sent. Spammers can easily fake a return path. See Email spoofing explained for guidance on detecting fraud email.
- Message-ID A unique identifier assigned to a message. The Message-ID is useful for diagnosing a duplicate email issue. If you compare the Message-ID for multiple emails, and the IDs match, you know those messages are duplicates.
- X-Originating-Ip: The IP address of the computer that sent the message. While this is slightly more difficult to fake, it is still possible. The originating IP address is typically the most reliable information about where the message actually came from. See Email spoofing explained for guidance on detecting fraud email.
