Show HN: Sanitising Email (www.grepular.com)

A developer has introduced an open-source project named Sanimail, enhancing email privacy and security beyond traditional PGP encryption. Inspired by advancements in AI and large language models (LLMs), Sanimail builds on a previous Perl script called gpgit, adding features like inlining remote content to combat pixel tracking, sanitizing HTML/CSS/SVG elements based on user-defined policies, and removing tracking parameters from links. This toolkit allows users to augment email safety by disarming privacy-invasive headers and implementing policy-driven sanitization, addressing vulnerabilities in conventional email clients. Sanimail's significance lies in its robust approach to email privacy, especially as digital communication increasingly faces threats of tracking and exploitation. Key technical features include options for inline remote content fetching through proxies (including Tor), image optimization to reduce email size, and flexible policy management for sanitized HTML elements. Users can not only encrypt their emails but also manage how external content and tracking information are handled, elevating the control individuals have over their email privacy. As a result, Sanimail provides a comprehensive solution for the growing concern of email security in an era where personal data tracking is pervasive.
