[Dovecot] How to give system and virtual users their own mail_location?

Hi all.

Now hopefully as a new thread because I still have this question. Apologies to Geert and Timo for my misbehaviour...(repling to the list and changing the subject).

I hace Dovecot rc12 working on Mandriva 2007.0 now for system accounts and virtual accounts both imap and imaps can be used. Th problem now is that I cannot use both types of user at the same time. The 'mail_location = ' strings are very different: Real system users have their Maildir in /home/%u/Maildir/ but virtual users have their maildir in /home/virtual/%d/%n/. How can tell dovecot to use the first for /etc/passwd clients and second for mysql authenticated clients? Just adding two private namespaces does not work. That is for ONE user having more mailbox locations, isn't it?

Thanks for any hints!
