About InLook

InLook is a small, fast viewer for .eml email files (the standard RFC 822 / MIME format used by Outlook, Thunderbird, and most other mail clients when saving a single message to disk). It renders headers, body (HTML or plain text), and attachments, with embedded HTML sandboxed under a strict Content Security Policy — no remote loads, no tracking pixels. Follows the system light/dark theme, registers as the default .eml handler, and never touches the network. Free Software from Struis ICT.
