[Dovecot] Mail root to root and permissions problem

[Antonello Onida]

In various point of the instructions can read that dovecot is only for 
dovecot internal use, and as user it must not have any permission!
My problem is related to the deliver of local mail, such as mail to root 
from root sent by cronjob!
I tried also to send a mail from root at localhost to vmail at localhost and 
the problem is the same...

Maybe internal mail don't pass through dovecot-postfix?!?!?
