Customize spam filter settings

This feature isn't available in the legacy free edition of Google Apps.

Incoming email messages are subjected to Google's spam filters, which automatically place messages detected as spam in a user's Gmail spam folder. Using the Spam setting, you can customize your organization's spam filters in the following ways:

  • Turn on aggressive spam filtering to enforce a more stringent filtering of bulk mail.
  • Create an approved sender list to bypass Google's spam filters. You can approve specific senders based on the email address or domain. You can also approve all internal messages within your organization.

Similar to other advanced Gmail settings, the Spam setting applies to all users in an organizational unit. Users within child organizations inherit the settings you create for the parent organization.

After you configure an advanced Gmail setting, it may take up to one hour for that configuration to propagate to individual user accounts. You can track prior changes with the Admin console audit log.

About approved senders

You can reuse approved sender lists across different settings. For example, you can specify the same approved sender list in both the Spam setting and Blocked senders setting, and it would modify the behavior of both settings.

The approved sender/bypass spam filter option applies to incoming mail only.


  • When you enter addresses or domain names, Gmail checks these against the From: part of the message header, not the envelope sender (or Return-Path section of the message header). Therefore, the From: sender must exactly match an address or domain you enter.
  • In some cases, "super spammy" messages sent from approved senders can still be marked as spam and delivered to recipients' Spam folder. Also, if a message from an approved sender contains a virus or is part of an email attack, Google's virus filters will still prevent it from reaching your users.
To customize spam filter settings
  1. Sign in to the Google Admin console.
  2. From the dashboard, go to Apps > G Suite > Gmail > Advanced settings.
  3. In the Organizations section, highlight your domain or the organizational unit for which you want to configure settings (see Configure advanced settings for Gmail for more details).
  4. Scroll down to the Spam section:
    • If the setting's status is Not configured yet, click Configure (the "Add setting" dialog box displays).
    • If the setting's status is Locally applied, click Edit to edit an existing setting (the "Edit setting" dialog box displays), or click Add another to add a new setting (the "Add setting" dialog box displays).
    • If the setting’s status is Inherited, click View to view the inherited setting, or click Add another to add a new setting (the "Add setting" dialog box displays).
  5. Enter a description for this configuration—for example, Spam setting for engineering.
  6. To configure spam filtering to be more aggressive, check the Be more aggressive when filtering bulk mail box. If you check this box, Gmail’s spam filter is more likely to decide that a message is spam. As a result, fewer spam messages should arrive in your users' Inbox. However, checking this box may also result in more non-spam messages being sent to your users' Spam folder.
  7. To set up an approved sender list, select either or both of the following options:
    • To bypass spam filters for messages received from internal senders (from users in the same organization), check the Bypass spam filters for messages received from internal senders box.
    • To bypass spam filters for messages received from addresses or domains specified in your approved sender lists, check the Bypass spam filters for messages received from addresses or domains within these approved senders lists box.
    • To send messages that meet your spam filter criteria to an admin quarantine for review, check the Put spam in administrative quarantine box. If you check this box, spam messages will never be directed to users' spam folders (or Message Center, in the case of a non-Gmail mailbox). A message released from admin quarantine is delivered directly to the end user's inbox or non-Gmail mailbox.
  8. If you checked the second box in step 7 (to set up an approved sender list), do the following:
    • Click Add or create a new one to create a new approved sender list.
    • To use an existing list as your approved sender list, click the list name.
    • To create a new list, enter a name for the list in the Create new list field, and then click Create.
    • To edit one of your lists, hover over the list name, click Edit, and then do the following:
      • To add email addresses or domains to the list, click Add.
      • Enter an email address or domain name (for example,
        Note: Check the Do not require sender authentication box to bypass the spam folder for approved senders that do not have authentication, such as SPF or DKIM enabled. Use this option with caution as it can potentially lead to spoofing.
      • When you're finished making changes, click Add setting or Save to close the dialog box.
      • Repeat these steps to add more email addresses or domains to the list.
  9. When you're finished making changes, click Add Setting to close the dialog box.
    Note: Any settings you add will be highlighted on the Advanced settings page.
  10. Click Save changes at the bottom of the Advanced settings page.
