Hello, we are in the process of setting up Email Notification Alerts for vSphere 7 and we are currently having issues with receiving the emails. We have the SMTP username and password configured under 'Advanced Settings' and we want to use port 587 (STARTTLS). We are currently seeing the following messages:
sendmail status:

Are there any additional setup that is needed for vSphere in order to gmail to accept these emails?
Thanks,
