MimeKitLite 3.1.0
MimeKit is an Open Source library for creating and parsing MIME messages. 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.

No packages depend on MimeKitLite.
* Always use a lowercase domain name in the Message-Id to work around bugs in eM Client. (issue #734)
* Improved handling of parsing Content-Types like "multipart/multipart/mixed; boundary=...". (issue #737)
* Added a maxLineLength argument to the QuotedPrintableEncoder .ctor.
* Added maxLineLength arguments to EncoderFilter.Create() methods.
* Fixed MimePart.Prepare() to remember the maxLineLength argument value for later use in the WriteTo() implementation. This maxLineLength value can then be passed to the Base64 or QuotedPrintable encoder so that it can properly limit lines to that length (up to a max of 76 characters as per the specs). (issue #743)
* Added net6.0 to the list of TargetFrameworks.
