[CentOS] Help Getting Postfix relaying via Gmail

Hi,

I am trying to get a CentOS 6 system relaying mail via my G-Mail account.
I followed the instructions found at
https://www.zulius.com/how-to/set-up-postfix-with-a-remote-smtp-relay-host/but
there seems to be a problem with authentication.  I have done some
research but still can't get this working.  Any suggestions ?  It seems the
user and password are correct.
