Connection error on e-Newsletter

Hi, I have installed e-newsletter plugin but I cannot configure Outgoing SMTP Email Settings. I am using it with a gmail business account “hello@fac****.com”. When I test connection I get the following error:

Failed to send test email! - Please check your outgoing email settings and server config to see if selected ports are open. Error details: The following From address failed: hello@fa*****.com : MAIL not accepted from server,530,5.5.1 Authentication Required. Learn more at

530 5.5.1 https://support.google.com/mail/?p=WantAuthError j128sm11215818wmd.12 - gsmtp

I have put the following values on settings:
Email Sending Method: SMTP
From email: hello@fac****.com
SMTP Outgoing Server: smtp.gmail.com
SMTP Port: 587
Secure SMTP?: TLS

I tried to test it also with my personal gmail account but I get the same error

I have also configured Gmail SMTP plugin without any problem, so SMTP is working.
