Description: The email header is a crucial section found at the beginning of an email message. It contains essential information about the sender, recipient, date and time of sending, as well as details about the routing of the message through mail servers. This information is presented in the form of fields, including ‘From’ (sender), ‘To’ (recipient), ‘Subject’ (email topic), and other technical fields like ‘Received’ that show the email’s journey. Headers are fundamental for identifying and authenticating emails, allowing users and security systems to verify the legitimacy of a message. Additionally, headers may contain information about the type of content and format of the message, which helps email clients to process and display the content correctly. In the field of digital forensics, analyzing email headers is a vital tool for tracing the origin of a message, identifying potential fraud or phishing attacks, and reconstructing communication between parties involved in an investigation. Therefore, email headers are not only a technical component but also play a crucial role in the security and integrity of electronic communications.
