Magma is a fully-featured, commercial-grade email server with support for SMTP, POP3, IMAP, HTTP, and an internal protocol MOLTEN. Support for the DIME ecosystem of advanced encryption protocols is currently in active development. Originally created by Ladar Levison for lavabit.com, Magma has since become a fully free and open source project. Magma's source code is available on Github and anyone who wishes to contribute code or submit bug reports is welcome to do so.
Whether you are an individual, SME, or corporate enterprise, the Lavabit technical team can assist with your implementation and development needs.
