[Dovecot] Dovecot - Vpopmail subdirectories

[Yacoubi Mohamed]

Hello, 

I have several thousand domains on a server. 
I'm doing now migration to Dovecot to replace courier-authlib. 

Some email accounts are in subdirectories that are automatically created
by vpopmail. 

Example: 
/ var/vpopmail/domains/0/domain.com 

How do I configure Dovecot?
