MailXaminer MIME Header Analyzer is a digital forensics tool designed to parse and analyze MIME (Multipurpose Internet Mail Extensions) header fields from email messages across a wide range of email file formats and clients. The tool is intended for use by digital forensic examiners, cybersecurity investigators, and legal professionals who need to examine email data for evidence of tampering, phishing, spam, or other criminal activity. Key analytical capabilities include inspection of MIME header fields such as MIME-Version, Content-Transfer-Encoding, Content-Description, Content-Disposition, and Content-Type. The tool provides multiple viewing modes including property view, MIME view, and hex view. It supports over 20 email file formats including PST, OST, EDB, OLM, MBOX, NSF, LX01, and MSG, as well as various desktop and web-based email clients. Additional analysis features mentioned include link analysis and timeline analysis. The tool can identify whether modifications have been made to email headers or attachments, which is useful for establishing the authenticity of email evidence. A free trial version is available that allows MIME header analysis but restricts data export functionality. The full commercial version enables export of analyzed data to other file formats.
