[Dovecot] INBOX permissios woes

[Josep L. Guallar-Esteve]

Hello, 

I have a dovecot system that uses winbind authentication
against Active Directory. I set it up by following the directions in the
wiki. That works great. 

When a new user receives an email, the inbox
is created with permissions 600 (rw- --- --) and ownership user:mail ,
even though I did chmod 02770 /var/spool/mail. And then, when dovecot
tries to access the inbox, it throws the error: 

Oct 29 13:47:59
imap-login: Info: Login: user=<user1>, method=PLAIN, rip=10.0.0.6,
lip=10.0.0.26, mpid=29047, secured
Oct 29 13:47:59 imap(user1): Error:
stat(/var/mail/user1) failed: Permission denied
Oct 29 13:47:59
imap(user1): Error: stat(/var/mail/user1) failed: Permission denied


Accessing users' Sent, Trash, creating new folders.... all that works
fine. 

I've been looking at the documentation, reading the wiki,
searching on google, asking on IRC. 

If you have any hint or
documentation that I've must have overlooked, please let me know.


Here's my dovecot information:
