The docs state that virtual mailbox, need some extra suff set up,  
namely virtual_mailbox_base.

How would this help with several backends?
I can't define several cyrus backends, can I?

And how exaclty does virtual_mailbox help in this scenario, since mail  
must be routed to the appropriate backend, which might be in another  
server, and for what I see in the docs, the virtual_mailbox requires  
the physical paths to the mailboxes, correct?

And will an address like username at domain.tld@backend be routed  
correctly with virtual_mailboxes?

Please some help for someone who's strugling with this for quite some  
days now.
