Integration

Hi,
We were trying to configure 'Generic Email' delivery channel for outbound agreement
We are trying to use gmail as our Mail host

We got below error:
Message Transmission Transport Exception
Transport Error Code is OTA-SMTP-1001

Configuration is:

Could you please suggest a solution for this
For error in some posts , it was suggested to set property "mail.smtp.starttls.enable" to "true" for this kind of error, could you tell us what would be its equivalent in B2B
