Designed for integration into a backend app to provide email client access.
Features a simple API for implementing your own email storage by implementing golang interfaces. Currently a dummy (in-memory) storage is included, with plans to include MySQL storage. This makes it simple to integrate into a backend application to allow users to drag-drop emails into the application, without messing around with maildir.
Although it would be possible to implement and plug in a maildir storage interface, that would defeat the purpose of this project and there are much better, tried and tested open source and commercial solutions that have been around for a long time (Courier, Dovecot etc). The goal of this project is to provide simple IMAP access to some kind of existing system without the overhead of installing a full-blown IMAP/POP3 mail server.
