Google Workspace (formerly G Suite) provides robust spam filtering tools that can be customized and managed through the Google Admin console.

Accessing Spam Filter Settings

1. Sign in to the Google Admin console using your administrator account.

2. Navigate to:

   • Menu → Apps → Google Workspace → Gmail → Spam, Phishing, and Malware.

3. On the left, select the organizational unit (OU) you want to configure. Settings can be applied at the domain or OU level.

Configuring Spam Filtering Options

• Click Configure or Add another rule in the Spam section.

• In the Add setting box, enter a unique name for your spam filter rule.

• Choose from various spam filtering options, such as:

  • Adjusting the aggressiveness of spam detection.

  • Creating content compliance rules.

  • Setting actions for detected spam (quarantine, delete, modify subject, etc.).

Allowlisting (Whitelisting) and Blocklisting

• Email Allowlist: To ensure emails from specific IPs, domains, or addresses are never marked as spam, use the allowlist option:

  • Click on Email allowlist and enter the IP addresses or domains to always allow.

  • Save your settings.

• Blocked Addresses: Specify addresses or domains you want to block. You can also configure whether to notify senders when their emails are rejected.

Bypassing Spam Filters for Approved Senders

• To bypass spam filters for messages from certain senders or domains:

  • In the Spam section, click Configure or Add another rule.

  • Check the boxes for “Bypass spam filters for messages from senders or domains in selected lists” and “Bypass spam filters and hide warnings for messages from senders or domains in selected lists”.

  • Assign an existing list or create a new address list for these senders or domains.

  • Save the rule and allow up to 24 hours for propagation.

Advanced Spam Filtering Options

• Enhanced Pre-delivery Message Scanning: Enable this to allow Google to perform additional scans on suspicious messages, which may introduce a short delivery delay but improves spam detection.

• Inbound Gateway: If using an external mail gateway, configure the inbound gateway settings to ensure proper spam evaluation and delivery. Add the gateway IPs and adjust header-based spam detection as needed.

• SPF, DKIM, DMARC: Implement these DNS records to improve your domain’s email authentication and reduce spam/phishing risks.

Monitoring and Reporting

• Use the Spam filter report in the Admin console to monitor spam activity, view quarantined messages, and adjust settings as needed.
