FW: I-D ACTION:draft-vaudreuil-mdnbis-00.txt

The following ID announcement is for a revision to the MDN specification in
preparation for Draft Standard.  Please note:  Many seemingly unimplemented
dispositions and all disposition modifiers have been removed.  If someone
can name TWO interoperable implementations of any of the deleted
dispositions or disposition modifiers, I will be happy to add them back into
the document.

Note that the requirements for draft standard are explicit that all features
and options need to have at least two, interoperable implementations.  If
they are still useful, the unimplemented dispositions deleted from this
document may be standardized at a later date as an MDN extension.  

This document also adds an additional section for gateway advice.  The
previous document was silent about what to do when gatewaying a MDN request
into a foreign network.  Given that most email networks do not have a
separate disposition-notification-to: recipient, that was a bit of an
oversight.

Please review and send comments.  It is my hope that we can quickly advance
this to Draft Standard. 

Thank you.

Greg Vaudreuil.
