Do you mean you've implemented your own storage backend to Dovecot?
Yep, we implemented storage backend to Dovecot. Now Dovecot is compatible with our storage system, and it works for about 3 mln users (or even more) :]

OK, then I think you'll just have to end up patching that small part of Dovecot. Supporting NIL separator seems like more trouble than worth. Maybe you can also do something similar to how Maildir++ works, just decide that e.g. ^ character is a hierarchy separator and have Dovecot use that?
