1.4 Relationship to Protocols and Other Algorithms

This algorithm is intended to permit the transmission of rich message property information over transports that have no mechanism for representing that information natively.

The output of the algorithm can be included in any of the following:

  • A file attachment (winmail.dat).

  • A MIME body part, as described in [RFC2045], using the "application/ms-TNEF" media type.

  • As an addition to the transmitted plain text message body using UUENCODE, as described in [MSDN-UAF], or a similar method to be decoded at the recipient end.

  • A transmission from the sender to the recipient using whatever means are provided by the protocol employed in transmitting message information between them.

Specifically, this algorithm transmits message data over Simple Mail Transfer Protocol (SMTP), Post Office Protocol - Version 3 (POP3), Internet Message Access Protocol - Version 4 (IMAP4), or other Internet protocols that incorporate MIME, as described in [RFC2045].

For conceptual background information and overviews of the relationships and interactions between this and other protocols, see [MS-OXPROTO].
