An email headers extractor is a tool or script designed to parse and retrieve the metadata contained in the headers of an email. These headers include vital information such as the sender's and recipient's email addresses, the subject of the email, timestamps, and routing details. By extracting email headers, one can analyze the email's origin, verify its authenticity, and troubleshoot delivery issues. This process is crucial for cybersecurity, as it helps identify phishing attempts and spam.
Additionally, it aids in compliance and legal investigations by providing a clear trail of the email's journey through various servers.
