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
'j...@example.com' from UTF-8 to UTF-7 (as defined in RFC3501) the mailbox or
hierarchy level is still 'j...@example.com'. 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?
