This version takes into account the latest feedback. As there
hasn't been much since the 4871bis debates took over, it seemed
like a good point to post a revision.
Chiefly the feedback was from Charles pointing out that the
verifier/receiver filtering action was not being represented
consistently. The rest was largely typos.
I have two issues:
*scope*
Apparently, there is consensus that "Discussion lists and broadcast
lists are not the same thing" [WV]. Section 3.2 exemplifies
newsletters and bulk marketing mail as "authoring" MLM modes. In
facts, most of the advice covers mailing lists proper. Should
ESP-lists be removed from the I-D entirely, e.g. by saying they are
not covered right after their definition?

*re-signing*
After recent discussions, it seems inadvisable that "A DKIM-aware
resending MLM is encouraged to sign the entire message". In
particular, section 5.7 may suggest that fields that had not been
signed by the author domain neither be signed by the MLM, unless the
MLM itself introduced or modified them.
Generic advice, such as the possibility of dropping unsigned fields,
will probably be added to 4871bis. It may or may not be worth
repeating it here.
