Invalid mailbox name

Hi,

The allowed ASCII-Chars are defined in the macro GOODCHARS in imap/mboxname.c
(https://github.com/cyrusimap/cyrus-imapd/blob/master/imap/mboxname.c#L1495).
non-ASCII-Chars are handled by RFC 3501 5.1.3.

This subject has been discussed a few years ago on this list, and GOODCHARS
has been changed between cyrus versions.

2.2:    #define GOODCHARS "  
+,-.0123456789:=@ABCDEFGHIJKLMNOPQRSTUVWXYZ_abcdefghijklmnopqrstuvwxyz~"
2.3:    #define GOODCHARS "  
#$'+,-.0123456789:=@ABCDEFGHIJKLMNOPQRSTUVWXYZ_abcdefghijklmnopqrstuvwxyz~"
Master: #define GOODCHARS "  
#$'()*+,-.0123456789:=?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[]^_abcdefghijklmnopqrstuvwxyz~"
