Equinox provides means to embed email messaging support into .NET and/or Mono runtime applications.
Since the library contains a custom LINQ provider it heavily depends on the LINQ extensions as well as some features introduced with .NET 4.0, it requires at least the .NET 4.0 Framework or the 2.8 Mono Runtime.
The .NET Micro Framework is not supported since it lacks almost all security features as SSL,RSA,SHA which are used extensively throughout the project.
The library supports basic and some advanced operations for the IMAP, SMTP and POP3 protocols. A precise listing can be found here.
The documentation for the project as well as the source code can be found directly on CodePlex.
