That's right.

But, the IMAP spec does not specify the delimiter! That does the 
implementation. When the clients converts a mailbox or hierarchy level named 
'[EMAIL PROTECTED]' from UTF-8 to UTF-7 (as defined in RFC3501) the mailbox or 
hierarchy level is still '[EMAIL PROTECTED]'. Is it possible to configure 
courier imap and specify the delimiter character? I guess not.
What do think is the better way with respect to the IMAP protocol:
1. Define an implementation dependent escape sequence if a user uses the 
delimiter character in a mailbox name or hierarchy level
2. Make the implementation be configurable to set the delimiter.
In my opinion 1 is the better approach because 2 just shifts the problem from 
one character to another.


But I understand what you mean. The use of the escape sequence needs to be 
specified by the IMAP protocol or one of its extension, right?
