REFERENCES

Transport Neutral Encapsulation Format (TNEF) is a Microsoft proprietary method for encoding Rich Text Format (RTF) messages that are sent across the Internet. A TNEF-encoded message contains a plain text version of the message, an attachment that contains the RTF version, and any OLE objects such as pictures or other attachments that were sent with the message.
