Known issues in rfc2821bis-01

Hi.

In addition to the "trailing period" issue now under discussion, 
I'm aware of four other issues/ questions in rfc2821bis-01 as 
posted before IETF.  At Tony's request, each is discussed in a 
separate note; please preserve the subject line up to and 
including the issue number when you reply.
I have deliberately avoided identifying the sources of the 
suggestions in this note in the hope that we can evaluate the 
issues and not the submitter.
I am retroactively assigning Issue 001 to the trailing period 
topic.
If you generate additional issue numbers, please start them with 
010.
