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 (more than 25x faster than OpenPOP.NET and over 100x faster than AE.Net.Mail and MailSystem.NET).

     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 massive limitations or bugs.

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

* Fixed message reserialization after prepending headers. (issue #524)
* Added a ContentType.CharsetEncoding property. (issue #526)
* Allow empty prop-spec token values in Authentication-Results headers. (issue #527)
* Added logic to quote Authentication-Results pvalue tokens if needed.
* Added support for converting RSACng keys into BouncyCastle keys for net4x versions that support it.
* Added support for RSAES-OAEP for the BouncyCastle backend. (issue #528)
* Updated and changed the API for RSASSA-PSS. CmsSigner now has a RsaSignaturePadding property which obsoletes the previous RsaSignaturePaddingScheme property.
* Added more columns to the default SQLite database CERTIFICATES table that allow more optimal SQL searches for certificates given various matching criteria.
* Fixed WindowsSecureMimeContext.Decrypt() to make sure it doesn't stop at the first failed recipient. (issue #530)
* Fixed splitting and reassembly of message/partial messages.
* Improved handling of Office365 Authentication-Results headers by adding a Office365AuthenticationServiceIdentifier property to the AuthenticationMethodResult class.
* Fixed mailbox address parser to be more lenient about `"["` and `"]"` characters in the display-name. (issue #532)
