Ok, your first post was right. Everything works right. But not with the configuration that was set when I got that box, so I deleted postfix and dovecot and once they were reinstalled after the basic configuration they worked.
The mails were sent as the AD user, and retrieved as the AD user.
Dunno which of the config parameters messed that but... it's solved now.
