Re: [IMAP] APPEND Command Usage

Yes, I agree with your comments. Existing functionality should be broken with this new proposal. 

But the TOOBIG response syntax does not convey the size supported by the server 

resp-text-code =/ toobig-response-code / badurl-response-code
toobig-response-code = "TOOBIG"

Reusing the TOOBIG response code with updated syntax like below solves the issue

toobig-response-code = " TOOBIG " [SP nz-number]
resp-text-code /=  toobig-response-code

Please share your comments.

Regards,
Jay

Subject: Re: [imapext] [IMAP] APPEND Command Usage

If I'm understanding the proposal correctly, a server that has already implemented CATENATE and now implements APPENDLIMIT is left in an ambiguous state whenever the limit is exceeded. If it returns [TOOBIG], then it's not compliant with the APPENDLIMIT recommendation. If it returns [APPENDLIMIT x] then it's returning an unexpected response to clients that have yet to implement APPENDLIMIT, thereby "breaking" 
existing functionality.
