Okay, thanks for the clarification.

Come to think of it, any hint how I can implement the existing scheme?

user_attrs =
        xxxMailbox=mail=maildir:/home/mailstore/%U$/Maildir:INDEX=/home/mailstore/indexes/%1U$/%U$,
	xxxMailbox=home=/home/mailstore/%U$

the maildir location is easy (mail=maildir:~/Maildir), but the index is
hard, as I don't have the userid in any variable.

The only thing I can come up with atm is

user_attrs = 
	xxxMailbox=home=/home/mailstore/%U$,
	xxxMailbox=mail=maildir:~/Maildir:INDEX=/home/mailstore/indexes/%16.1h/%16.99h

but I'm willing to bet that this is going to break at some point, the
latest point being when someone changes the mailstore path and forgets
to update the offset :-\

What happens when the width is larger than the length of the string
anyway?
