KTNEF - an API for handling TNEF data.


The ktnef library contains an API for the handling of TNEF data.

The API permits access to the actual attachments, the message properties (TNEF/MAPI), and allows one to view/extract message formatted text in Rich Text Format format.


To quote Wikipedia:

"<em><b>Transport Neutral Encapsulation Format</b> or \b TNEF is a proprietary format of e-mail attachment used by Microsoft Outlook and Microsoft Exchange Server. An attached file with TNEF encoding is most usually called winmail.dat or win.dat. Within the Outlook email client TNEF encoding cannot be explicitly enabled or disabled. Selecting <a href="https://en.wikipedia.org/wiki/Rich_Text_Format">RTF</a> (Rich Text Format) as the format for sending an e-mail implicitly enables TNEF encoding, using it in preference to the more common and widely compatible \b MIME standard. When sending plain-text or \b HTML format messages, Outlook uses MIME. Some TNEF files only contain information used by Outlook to generate a richly formatted view of the message, embedded (\b OLE) documents or Outlook-specific features such as forms, voting buttons, and meeting requests. Other TNEF files may contain files which have been attached to an e-mail message.</em>"
