On February 10, draft-harrison-email-tracking-00.txt was announced on the ID-announce mailing list. Assuming that the draft is not intended to be a precursor of an April 1 RFC, I have several comments. Since the draft mentions no place for public discussion, I am copying the IETF discussion list, with a suggestion that any public discussion take place there, unless and until a more suitable venue is proposed. First, the draft seems to be in far too premature a state to warrant detailed commentary, so I'll touch on several issues in general terms. o The subject matter of the draft appears to be covered more appropriately and far more comprehensively by RFCs 3885 through 3888. I believe that publication as an RFC would be harmful to the IETF work done in the MSGTRK WG. o It proposes a header field, which it confusingly calls a "header", but provides no ABNF and no textual indication of syntax or semantics. o It refers to an "originator", but does not specify the source of that information, nor what should happen if the SMTP envelope return path or other source of "originator" is a null path. o It mentions "return receipt", but provides neither a normative nor informative reference. o It purports to turn the "only human-readable" Subject field comprised of unstructured text into a repository for keywords in a specific language, with no provision for localization or registration of keywords. o The proposed field uses a portion of the header field namespace reserved for MIME extension fields, but the field is not claimed as a MIME extension field, nor is there is either a normative or informative reference to the MIME specifications. o No header field registration information is provided. o Overall, the proposal is so nebulous as to defy any attempt at implementation. o There is no discussion of interaction with deployed mechanisms, including gateways (e.g. to/from X.400), message/partial fragmentation, or resent messages. o The draft lacks the mandatory Security Considerations section. o Although the draft uses the English-language word "TRACK" in a message header field, there is no provision for internationalization or localization and no Internationalization Considerations section. o Although a keyword is proposed, there is no IANA Considerations section. o There is a single "References" section, improperly formatted, and with no indication of whether the single reference (N.B. not plural) listed is normative or informative.
