For 2-11 I had smtp_relay with same issue then gave up did complete reinstall with 2-9 with correct change to smtp_recipient_restrictions and same issue from thunderbird but not mutt. I then commented out the restrictions, reloaded postfix and everything worked. I then added the commas and uncommented the line and reloaded postfix.
