This library implements a simple "filesystem" inside an IMAP folder. The filesystem can be symmetrically encrypted (using the cryptography library's AES-128 Fernet construct), it supports concurrent readers/writers and file versioning. The motivation for this tool is that an IMAP account is the most commonly available form of standards compliant "cloud storage" available to the general public. This makes an IMAP account a compelling location for app backups or basic synchronization, and Mailfile's sister project, Mailpile, needs exactly such features.

FUSE compatible using fusepy.

Python v2.7, unfortunately.
