As a G Suite admin, you can help Gmail identify suspicious content by enabling enhanced pre-delivery message scanning.
When Gmail identifies that an email may be phishing, it might show you a warning or move the email to Spam. Enhanced pre-delivery message scanning improves how to identify suspicious content.
When Gmail detects suspicious content, it introduces a short delivery delay to perform additional checks. Gmail does this through a setting that can be turned on in your Admin console.
Enable enhanced pre-delivery message scanning
From the Admin console Home page, go to AppsG SuiteGmailAdvanced settings.
Tip: To see Advanced settings, scroll to the bottom of the Gmail page.
- Select your top-level organization.
- Scroll to the Enhanced pre-delivery message scanning setting.
- Check the box to apply the setting to your domain, or uncheck the box to turn the setting off.
