Thanks a lot, now it works!

Weird figure, i didn't saw that article...

But now i've got a new problem:

==============================
dovecot: Jun 15 17:03:33 Error: imap(ced at example.org): Ambiguous mail
location setting, don't know what to do with it:
example.org/ced at example.org/ (try prefixing it with mbox: or maildir:)
dovecot: Jun 15 17:03:33 Error: imap(ced at example.org): Failed to create
storage with data: example.org/ced at example.org/
dovecot: Jun 15 17:03:33 Info: imap-login: Login: user=<ced at example.org>,
method=PLAIN, rip=192.168.70.1, lip=192.168.0.101
dovecot: Jun 15 17:03:33 Error: child 3848 (imap) returned error 89
==============================

It seems that dovecot ignore the directive in my dovecot.conf:

default_mail_env = maildir:/home/mbox/%d/%u

I've tried to change it as:
default_mail_env = /home/mbox/%d/%u
default_mail_env = 

but i've got always the same error message.

The directory was correctly created by postfixadmin:

==============================
server01:/home/mbox # ls -la
total 12
drwxrwx--x 3 postfix postfix 4096 Jun 15 14:36 .
drwxr-xr-x 5 root    root    4096 Jun 12 15:52 ..
drwx------ 3 postfix postfix 4096 Jun 15 14:36 example.org
==============================

Any ideas?

Thanks a lot in advance
