Ok, I authenticate with full email addresses and there's not user1 on /etc/aliases... I've tried with another user and with non-encrypted passwords but still doesn't work. Do I need to configure DNS server or something that is not mentioned in the howto?
Edit: I don't know if this is important but every time I restart courier-authlib I see this on /var/log/maillog:
Feb 4 17:42:05 server authdaemond: stopping authdaemond children
