The IESG has approved the Internet-Draft 'SMTP Service Extensions for Transmission of Large and Binary MIME Messages' <draft-vaudreuil-esmtp-binary2-03.txt> as a Proposed Standard. This has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact persons are Patrik Faltstrom and Ned Freed. Technical Summary This memo defines two extensions to the SMTP service. The first service enables a SMTP client and server to negotiate the use of an alternative to the DATA command, called "BDAT" for efficiently sending large MIME messages. The second extension takes advantage of the BDAT command to permit the negotiated sending of binary contents wrapped in MIME but without a transport encoding. This document is replacing RFC1830 (Experimental RFC). Working Group Summary This was not a result of a wg effort, even though RFC 1830 was. This minor update to the document has been discussed on various mailing lists, and the intention is to move this SMTP extension from Experimental to Standards Track. There are some implementations of this extension. Protocol Quality The specification has been reviewed by Patrik Faltstrom
