Gmail sending mail problem

I have em Client 9.2.1222. What is the exact IMAP and SMTP setting in Gmail? I am trying various options in this but have problem in sending mails.

As a test, can you completely disable any anti-virus, firewall, proxy or VPN, then try send again.
Sometimes even restarting your router may resolve this.
