Welcome to Mailpile!


Development on this codebase has halted, until the Python3 rewrite has completed.

Apologies to those who have unanswered, out-standing pull requests and issues. Your efforts are appreciated!

If you rely on this code and have your own branch which you actively maintain, let us know: we would be happy to link to it.

If you need to run Mailpile v1 to access legacy data, consider using our legacy Docker images.

Introduction (Obsolete)

Mailpile ( is a modern, fast web-mail client with user-friendly encryption and privacy features. The development of Mailpile is funded by a large community of backers and all code related to the project is and will be released under an OSI approved Free Software license.

Mailpile places great emphasis on providing a clean, elegant user interface and pleasant user experience. In particular, Mailpile aims to make it easy and convenient to receive and send PGP encrypted or signed e-mail.

Mailpile's primary user interface is web-based, but it also has a basic command-line interface and an API for developers. Using web technology for the interface allows Mailpile to function both as a local desktop application (accessed by visiting localhost in the browser) or a remote web-mail on a personal server or VPS.

The core of Mailpile is a fast search engine, custom written to deal with large volumes of e-mail on consumer hardware. The search engine allows e-mail to be organized using tags (similar to GMail's labels) and the application can be configured to automatically tag incoming mail either based on static rules or bayesian classifiers.

Credits and License

Bjarni R. Einarsson ( created this! If you think it's neat, you should also check out PageKite: Smri and Brennan joined the team in 2013 and made this a real project (not just a toy search engine).

The original GMail team deserve a mention for their inspiring work: wishing the Free Software world had something like GMail is what motivated Bjarni to start working on Mailpile. We would also like to thank Edward Snowden for inspiring us to try and make PGP usable for journalists and everday folks!


And of course, we couldn't do this without our community of backers.
