Ghost can't send mail using Gmail (Google Apps)

I verified my domain, I added MX records, the user and password is correct.

mail: {
            service: 'Gmail',
            transport: 'SMTP',
            options: {
                host: 'smtp.gmail.com',
                port: 465,
                secureConnection: true,
                auth: {
                    user: '*******@my-domain.com',
                    password: '******'
                }
            }
        }

And I keep getting this error: “AuthError: Invalid login - 535-5.7.8 Username and Password not accepted. Learn more at 535 5.7.8 http://support.google.com/mail/bin/answer.py?answer=14257”

What else should I do?
