MIME Namespace
The Microsoft.Exchange.Data.Mime namespace provides classes that allow you to create, access, and modify MIME documents. You can work with MIME documents using either a stream-based or DOM-based method. The MIME namespace contains the MimeReader and MimeWriter classes, which provide forward-only, read and write access to MIME data streams. For DOM-based access to MIME data, the MIME namespace provides the MimeDocument class.
