# UNIX Hierarchy Convention
# Set to yes, and cyrus will accept dots in names, and use the forward
# slash "/" to delimit levels of the hierarchy. This is done by converting
# internally all dots to "^", and all "/" to dots. So the "rabbit.holes"
# mailbox of user "helmer.fudd" is stored in "user.elmer^fud.rabbit^holes"
