Hmm.  There is an issue with returning the JMAPACCESS response code if a 
server also wants to use the CAPABILITY response code for telling the 
client which capabilities are available post-authentication.  The IMAP 
grammer only allows one repsonse code in a tagged response, correct?

Perhaps rather than JMAPACCESS being a response code, its just a 
post-auth capability?
