Nevertheless, some coordination is needed.  The discussion in Section 7.1 of 
RFC 5321, "Mail Security and Spoofing", needs revision.  This question is 
already addressed in Appendix G.4, "Originator, or Originating System, 
Authentication" of John's I-D.

For RFC 5322, Dave's Author: and Sender: I-Ds might happen to become RFCs 
before rfc5322bis.  Can they be considered in that case?  Certainly, it won't 
make sense to publish contrasting specifications, such as, for example, the 
number of email addresses allowed in a From: field.
