[ietf-dkim] Possible C14N incorporating MIME decoding

[Bill.Oxley at cox.com]

Slight disagreement
" No. AIUI DKIM is supposed to operate mainly between the 1st MTA after
the  
sending MUA and the last MTA before the receiving MUA (though smarter
MUAs  
that sign their own, or verify their own are welcome to try)."

I would suggest that DKIM operates between the signing MTA and the edge
boundary MTA of the receiving domain that is the certifier of DKIM
signatures which may be a smart MUA but is more likely a filtering MTA
at the ISP.

Thanks,
