Mail header analyze

A mail header analysis!

A mail header is the part of an email message that contains metadata about the message, such as the sender, recipient, date, and other details. Analyzing a mail header can provide valuable information about the email's origin, routing, and potential security threats.

Here's a breakdown of the different components of a mail header:

1. From: The sender's email address.
2. To: The recipient's email address.
3. Subject: The subject line of the email.
4. Date: The date and time the email was sent.
5. Message-ID: A unique identifier for the email message.
6. Received: A list of servers that received the email, along with the date and time.
7. Sender: The sender's email address (may be different from the From field).
8. Reply-To: The email address to which replies should be sent.
9. Return-Path: The email address to which bounces and errors should be sent.
10. X- headers: Custom headers added by the email client or server.

When analyzing a mail header, you can look for the following:

• Spoofing: Check if the From field matches the actual sender's email address. Spoofing occurs when the sender's email address is forged to make it appear as if the email came from someone else.
• Spam: Look for keywords or phrases commonly used in spam emails. Check if the email contains suspicious attachments or links.
• Phishing: Check if the email is attempting to trick the recipient into revealing sensitive information, such as passwords or credit card numbers.
• Malware: Check if the email contains attachments or links that may contain malware.
• Routing: Analyze the Received headers to see which servers the email passed through and when. This can help identify potential security threats or email spoofing.
• Authentication: Check if the email has been authenticated using techniques such as SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), or DMARC (Domain-based Message Authentication, Reporting, and Conformance).

Some common tools used for mail header analysis include:

• Mail headers viewer: A tool that displays the mail header in a readable format.
• Email analysis software: Tools like Mailwasher, SpamAssassin, or ClamAV that analyze email headers and bodies for spam, malware, and other security threats.
• Network forensic tools: Tools like Wireshark or Tcpdump that capture and analyze network traffic, including email headers.

By analyzing a mail header, you can gain valuable insights into the email's origin, routing, and potential security threats. This can help you make informed decisions about whether to trust the email and take appropriate action to protect your email account and data.
