I'll answer to myself.
The problem was related to the FROM value and not the AUTH option value.
The smarthost (who has the domain2 as local domain) checked for the
username [EMAIL PROTECTED] into its users before it accepted the email, and
since the user was not there, it rejected the email.
Now the problem is solved.
