How to set up a spam filter

    Sign in to your Google Admin console.

    Sign in using your administrator account.

    From the Admin console dashboard, go to Apps >> G Suite >> Gmail >> Advanced settings.

    Tip: To see Advanced settings, scroll to the bottom of the Gmail page.

    (Optional) On the left, select an organization.

    Scroll to the Spam section, hover over the setting, and click Configure. If the setting is already configured, hover over the setting and click Edit or Add Another.

    For a new setting, enter a unique name.

    To configure more aggressive spam filtering, check the Be more aggressive when filtering spam box. If you select this option, it's likely that more messages will be marked spam and sent to your users' spam folders.

    To bypass spam filters for messages from users in the same organization, check the Bypass spam filters for messages received from internal senders box.

    To bypass spam filters for messages from addresses or domains specified in an approved sender list:

        Check the Bypass spam filters for messages received from addresses or domains within these approved senders lists box.

        Click Use existing or create a new one, enter a new list name, and click Create.

        To use an existing list as your approved sender list, click the list name.

    To add email addresses or domains to a list:

        Hover over the list name, click Edit, and then click Add.

        Enter an email address or domain name.

        Important: Use the Do not require sender authentication option with caution as it can lead to spoofing. The option bypasses the spam folder for approved senders that don't have authentication, such as SPF or DKIM, enabled.

        Click Save.

        Repeat the steps to add more email addresses or domains to the list.

    To send filtered messages to Admin Quarantine for review, check the Put spam in administrative quarantine box. If you select this option, spam messages are never directed to users' spam folders. If you are using the Message Center, spam messages aren't directed to the Message Center. A message that's released from quarantine is delivered directly to the user's Gmail inbox or non-Gmail mailbox.

    Click Add Setting.

    At the bottom of the Gmail Advanced setting page, click Save.
