No restrictions for SASL smtp auth clients

Hello Everybody,

Currently i have a postfix virtual configuration running out of the box,
it provides smtp auth relay support, however one of the smtpd_restrictions
i use in main.cf is:

permit_sasl_authenticated,
reject_unauth_destination <- THIS

that means that a mail to a user not found in a local hosted domain will
be rejected inmediately.

Since the 99% of the connections that use smtp auth are users sending
mail throught their own MUAs i like this restriction to not apply when the
client is authenticated, i prefer the system to send an email with a
mailer-daemon message explained the error, but not reject the email. The
normal user 90% of the time never read the error showed by the MUA and he
thinks the problem is the mail server, so i prefer to send an email
after that.

Is there any way to skip this restriction ?

Thanks.
