Jun  3 14:19:46 mx2 postfix/smtpd[20796]: NOQUEUE: reject: RCPT from unknown[10.2.2.80]: 550 5.1.0 <send-as-noreply@google.com>: Sender address rejected: User unknown in virtual mailbox table; from=<send-as-noreply@google.com> to=<hanna@XXXX> proto=ESMTP helo=<mail-lb0-x230.google.com>

The email address hanna@XXXX is legit and receiving emails fine, - but i think as send-as-noreply@google.com is not a real email address its somehow doing some sender verification and therefore rejecting it. This is a autorization email from google before a user can setup a pop connector to download there email into gmail.

Any ideas where to look?
