MimeKit 2.3.0

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

Release Notes

* Fixed MultipartRelated to fall back to the multipart/related type parameter when locating the Root. (issue #489)
* Improved Authentication-Results parser to handle non-standard syntax. (issue #490)
* When FormatOptions.AllowMixedHeaderCharsets is disabled, always use the user-specified charset. Previously this could/would still use us-ascii and/or iso-8859-1 if the entire header could fit within one of those charsets. (issue #493)
* Fixed the line length calculations in the BestEncodingFilter. (issue #497)
* Fixed Multipart to properly ensure the epilogue ends w/ a new-line when FormatOptions.EnsureNewLine is true. (issue #499)
* Modified Multipart.WriteTo[Async] to not ensure that a Content-Type boundary parameter has been set. This code-path was only hit if the multipart was parsed by the parser and did not have a boundary parameter in the first place. In the interest of preserving byte-for-byte compatibility with the original input, this sanity check has been removed. (issue #499)
