Gmail issues not sending mail a show stopper if not fixed

I am trying out your product on the 30 day trial and am having issues getting my gmail messages to send out. I keep getting errors not able to connect to gmail. My acct has connected and authenticated and sync’d without any problems but I can not send messages. I have also gone in and done diagnostic on smtp and it claims the issue is fixed but can still not send. Any help to resolve this would be appreciated.

Hi, could you make screenshot of your SMTP tab in Tools - Accounts - your account - SMTP tab.
