I think this would be the best way to do it,
because client can determine most easily if the server will honor a setting.

Yes, I knew, sorry for being unclear on this and thanks a lot for the

Let me add, that I believe that some intrusion detection systems 
or security version scanner will bark on such a change in the free-form banner
just because it is a change. So I would possibly revert it to IMAP4 again 
(assuming that most people will not yet have gotten to 2.3.12 or 2.3.13 which 
both have "IMAP".) Otherwise it has been in there in two versions so this 
software would just bark until fixed.
