Check TLS Encryption : this is important as Gmail accepts SMTP connection with SSL only.

7. In delivery tab, click on advance and provide the details (TIP Fully qualified name is your local server name not the web server or gmail server address in my case it is win-l3aqpjnvg2b.mydomain.com)

8. Now in SharePoint Central Admin we have to setup outgoing email settings with using local SMTP Server we just configured(TIP: i use  win-l3aqpjnvg2b.mydomain.com instead of test.corp.com)

I hope it helps you
