MimeKit is an Open Source library for creating and parsing MIME, S/MIME and PGP messages on desktop and mobile platforms. It also supports parsing of Unix mbox files.

     Unlike any other .NET MIME parser, MimeKit's parser does not need to parse string input nor does it use a TextReader. Instead, it parses raw byte streams, thus allowing it to better support undeclared 8bit text in headers as well as message bodies. It also means that MimeKit's parser is significantly faster than other .NET MIME parsers.

     MimeKit's parser also uses a real tokenizer when parsing the headers rather than regex or string.Split() like most other .NET MIME parsers. This means that MimeKit is much more RFC-compliant than any other .NET MIME parser out there, including the commercial implementations.

     In addition to having a far superior parser implementation, MimeKit's object tree is not a derivative of System.Net.Mail objects and thus does not suffer from System.Net.Mail's limitations.

     API documentation can be found on the web at http://www.mimekit.net/docs

* Added Import() methods for X509Certificate2 for all S/MIME contexts. (issue #784)
* Handle S/MIME sha# as well as sha-# micalg names for improved interop. (issue #790)
* Fixed the MemoryBlockStream.Read() method to handle cases where the length of the stream is longer than int.MaxValue.
* Fixed TnefPart.ConvertToMessage() to promote lone multipart/mixed subparts to become the message body much like it used to work pre-v3.2.0. (issue #789)
* Reduced memory usage when using SecureMimeContext.Compress() and CompressAsync().
* Dropped support for net452 and net461 now that their life cycles have ended and are no longer supported by Microsoft. (issue #768)
* Added support for net462.

Special thanks to Fedir Klymenko for his improvements to MemoryBlockStream and SecureMimeContext.Compress!
