- SMTPEXT Minutes
-
- This meeting began as a Birds of a Feather session called by Phill Gross
- (CNRI) to discuss two SMTP related proposals. Jan Michael Rynning
- (NORDUnet) and Johnny Eriksson (NORDUnet), participating by telephone,
- presented a method for transmitting eight bit character sets over SMTP.
- A proposal for a standard List-Service syntax for the Internet was made
- by Greg Vaudreuil (CNRI). The discussion broadened a bit and resulted in
- the formation of a Working Group to consider enhancements to SMTP and
- RFC 822 to allow for body parts.
-
- Rynning's and Eriksson's proposal suggested a mechanism to transmit 8
- bit character sets through SMTP. The proposal consisted of:
-
-
- o Eliminating the 7bit restriction in SMTP, and in cases where 8 bit
- SMTP is not implemented,
- o Proposing a 7 bit encoding for non-8 bit systems called TEX-HEX.
- TEX-HEX is a mixture of plain ASCII TEXT and HEX encoded
- characters.
-
-
- The group found the proposal interesting, but primarily as a starting
- point for a re-examination of several SMTP issues. There was a
- consensus that the group should work to eliminate the 7 bit and 1000
- character per line restrictions in SMTP. This will allow easier sending
- of binary files. Tom Kessler (SUN) convinced the group that there were
- only minor code changes required for sendmail to accept 8 bit ASCII.
- Kessler further volunteered to author a document describing the changes
- to the SMTP protocol. A command ``EBIT'' was proposed in the document
- by Rynning and Eriksson to identify new mailers. The group agreed that
- this extension should be considered for SMTP. An alternate HELO command
- could be defined to query a mailer for 8 bit compatibility, such as
- HELO8.
-
- The Working Group looked at RFC 1154 for defining encodings of specific
- body parts. Some felt that the document has short-comings in not
- differentiating between content and the encoding scheme. Greg Vaudreuil
- took an action to contact the author to inquire about the state of that
- document. The Working Group felt that establishing body parts for 822
- mail would be a good thing. An outstanding issue remained concerning
- the interaction between the various encoding schemes as the 7 or 8 bit
- transmission systems.

-
-
- Rynning and Eriksson took an action to re-write their proposal for
- TEX-HEX as a specific encoding and body part to be used with the
- encoding document.
-
- John Veizades (Apple) stopped in to brief the group about Unicos, a
- universal text encoding scheme developed at Zerox and Apple. This
- scheme used two octets to represent all known characters.
-
- Chris Myers (WashU) explained the list service offered by Washington
- University, and explained many of the features of Bitnet's ListServ.
- Myers took an action to distribute the listserv document to those in the
- group who had an interest. The group did not come to a consensus on
- whether to pursue this topic at this time.
-
- Actions
-
-
- Kessler Write a document amending RFC 821 to eliminate the
- line length restriction and the 7 bit restriction.
- Vaudreuil Determine the state of RFC 1154, and encourage the
- author to join in this effort.
- Eriksson/Rynning Rewrite the TEX HEX encoding document as a specific
- instance of an RFC 1154 body part.
