[Dovecot] mbox/maildir mixed setup with system/virtual mixed users

[Victor TARHON-ONU]

 	Hello Everyone,

 	I'm using dovecot 1.0.7 (not sure how relevant it is though) 
configured to handle both sytem users and virtual users.
 	The system users are handled by default (PAM), while the virtual 
users are handled pretty much like this:

   passdb passwd-file {
     args = /var/spool/vmail/%d/auth/%n
   }

 	...And mailbox and folder location settings:

   userdb static {
     args = uid=mail gid=mail home=/var/spool/vmail/%d/mail/%n mail=mbox:/var/spool/vmail/%d/imap/%n:INBOX=mbox:/var/spool/vmail/%d/mail/%n
   }

 	Everything works perfectly with the inbox and mail foder in mbox 
format.
 	Now, what I'm trying to accomplish is to reconfigure dovecot to 
create and handle the secondary mail folders (/home/user/mail for system 
users and /var/spool/vmail/domainname/imap/user/imap for virtual users) in 
maildir format.

 	I tried to define some name spaces to make this happen, but 
whatever I to do make one work (either the virtual users or the system 
users) would make the other non-functional.
 	By example, I have these name space definitions and the virtual 
users work fine with maildir:

namespace private {
         separator = /
         prefix = "#mbox/"
         location = mbox:/var/spool/vmail/%d/imap/%n:INBOX=/var/spool/vmail/%d/mail/%n
         inbox = yes
         hidden = yes
}
namespace private {
         separator = /
         prefix =
         location = maildir:/var/spool/vmail/%d/imap/%n
         hidden = yes
}

 	Maybe I didn't fully understand the namespace concept, but I was 
unable to make them apply only to one location of the imap folders 
locations or another.

 	Can anyone give me a hand with this, if this setup is even 
possible?
