Issue/Introduction

 You are integrating Email Security.cloud with Google Workspace for inbound emails.

Environment

Email Security.cloud

Resolution

Learn how to configure Google Workspace Business and Education editions with Symantec Email Security.cloud as your inbound email gateway.

To scan email from external sources, you must register the IP addresses or mail hosts of the points of entry into your network. These points of entry may be firewalls, routers, mail servers, or a public hosted cloud service.

The public hosted cloud services that we support are Google's Workspace Email and Microsoft Office 365. This information is for guidance only. You must retrieve up-to-date information from your public hosted service account to ensure accuracy. Your account information in the Google Workspace portal provides the inbound route information that you need to enter into the Email Security Services portal.

Inbound configuration

  1. In the Google Workspace Management console, navigate to Apps > G Suite > Gmail > Advanced settings (scroll to the bottom).
  2. In the left pane, select your top-level organisation (typically your primary domain).
  3. In the Spam section, hover over Inbound Gateway, and click on Configure to create a new setting.
  4. Enter a description: Symantec Email Security.cloud IP Ranges.
  5. In Gateway IPs, click Add, and add all of the IP address ranges for Email Security.cloud.
  6. You can select the following options based on your requirements:
  • Automatically detect external IP.
  • Reject all mail not from gateway IPs. This is recommended after the domain's MX record has been configured to point to Symantec's infrastructure.
  • Require TLS for connections from the email gateways listed above. This is recommended when ready to enforce TLS between Symantec and Google.
  1. Click Save.
  2. Click Save again.

Once you complete these steps, you can provision domains using the domain wizard in the Symantec.cloud portal under Services > Email Services > Domains. The Google Workspace MX records are needed for your inbound routes. This MX record is where Symantec delivers mail to after being processed by Email Security.cloud.

Whitelist Symantec.cloud IP ranges in Google Workspace

This will bypass any anti-spam scanning performed by Gmail on messages that have already been scanned by Symantec.cloud Infrastructure. However, any IP listed as Inbound Gateway will not be whitelisted if also added to the Email Whitelist. For the receiving IP, Gmail will use the first public IP not registered as an Inbound Gateway, found in the "Received: from" headers.

You can either add Email Security.cloud IP ranges as Inbound Gateway and use Gmail anti spam service (which can generate false positive verdicts), or add our IP ranges to your Email Whitelist to bypass all Gmail's Anti Spam scanning from our gateways.

  1. In the Google Workspace Management console, navigate to Apps > G Suite > Gmail > Advanced settings.
  2. In the left pane, select the top-level organization, and scroll to Email Whitelist in the Spam section.
  3. Add each of the public IP ranges of the Symantec Email Security.cloud service separated by commas. For example:
216.82.240.0/20,103.9.96.0/22,195.245.230.0/23,194.106.220.0/23,193.109.254.0/23,117.120.16.0/21,46.226.48.0/21,95.131.104.0/21,85.158.136.0/21,67.219.240.0/20
  1. Click Save.
