Since your relayhost setting is:

  relayhost = [smtp.gmail.com]:587

Your SASL password should (IIRC) be either:

      [smtp.gmail.com]:587 chris.pollock1...@gmail.com:*********************

or

      smtp.gmail.com chris.pollock1...@gmail.com:*********************

the version without the [], but the port might not work, as it is
neither the full destination, nor the underlying host.
