A preliminary evaluation has been made of SMTP Service Extension for 8bit-MIMEtransport [RFC1652] (Klensin, J., Freed, N., Rose, M., Stefferud, E., and D. Crocker, “SMTP Service Extension for 8bit-MIMEtransport,” July 1994.) by the Yet Another Mail (YAM) Working Group for advancing it from Draft to Full Standard. The YAM WG requests feedback from the IESG on this decision.
This Internet-Draft is not meant to be published as an RFC. It is written to facilitate processing within the IESG.
- Title:
- SMTP Service Extension for 8bit-MIMEtransport
- Link:
- http://tools.ietf.org/html/rfc1652
Time in Place:
- RFC2026:
- "A specification shall remain at the Draft Standard level for at least four (4) months, or until at least one IETF meeting has occurred."
- Published:
- July 1994
Confidence document meets RFC 2026 section 4.1.3 (Standard) test:
- RFC2026:
- "significant implementation and successful operational experience...[with] a high degree of technical maturity and [] a generally held belief that the specified protocol or service provides significant benefit to the Internet community."
In the 15 years since publication, this specification has become an integral part of all professional SMTP software products and is widely supported in Internet Mail operations. There are no RFC Errata on this specification.
The universal deployment of this feature is well-known to many YAM working group participants. In addition, the working group is obtaining explicit statements of deployment for specific SMTP implementations.
Proposed Changes (the YAM WG proposes making the following changes in a revision:
- RFC2026:
- "Minor revisions are expected, but a significant revision may require that the specification accumulate more experience at its current maturity level before progressing."
Remove reference to [RFC0974] (Partridge, C., “Mail routing and the domain system,” January 1986.)
Add reference to [RFC5321] (Klensin, J., “Simple Mail Transfer Protocol,” October 2008.). Use it to replace reference to [RFC0821] (Postel, J., “Simple Mail Transfer Protocol,” August 1982.).
Add reference to [RFC5234] (Crocker, D. and P. Overell, “Augmented BNF for Syntax Specifications: ABNF,” January 2008.). Use it to replace reference to [RFC0822] (Crocker, D., “Standard for the format of ARPA Internet text messages,” August 1982.). This is for ABNF specification.
Add reference to [RFC2045] (Freed, N. and N. Borenstein, “Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies,” November 1996.). Retain reference to [RFC1521] (Borenstein, N. and N. Freed, “MIME (Multipurpose Internet Mail Extensions) Part One: Mechanisms for Specifying and Describing the Format of Internet Message Bodies,” September 1993.).
Add reference to [RFC2046] (Freed, N. and N. Borenstein, “Multipurpose Internet Mail Extensions (MIME) Part Two: Media Types,” November 1996.). Retain reference to [RFC1522] (Moore, K., “MIME (Multipurpose Internet Mail Extensions) Part Two: Message Header Extensions for Non-ASCII Text,” September 1993.).
Remove reference to [RFC1651] (Klensin, J., Freed, N., Rose, M., Stefferud, E., and D. Crocker, “SMTP Service Extensions,” July 1994.). Replace it with reference to [RFC5321] (Klensin, J., “Simple Mail Transfer Protocol,” October 2008.).
Non-Changes (the YAM WG discussed and chose not to make the following changes):
None.
Downward references (At Full Standard, the following references would be downward references):
[RFC5321] (Klensin, J., “Simple Mail Transfer Protocol,” October 2008.), [RFC2045] (Freed, N. and N. Borenstein, “Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies,” November 1996.), [RFC2046] (Freed, N. and N. Borenstein, “Multipurpose Internet Mail Extensions (MIME) Part Two: Media Types,” November 1996.).
- NOTE:
- The YAM working group currently has the goal of also moving these documents to Full Standard.
The YAM WG requests feedback from the IESG on these decisions. In particular:
This document contains no IANA actions.
This document requests IESG feedback. There are no security considerations.
