In order to configure incoming filtering for G Suite follow these steps:

Step 1. Spam Experts Configuration:

After you have configured everything else you must now ensure that your MX records are pointing to Spam Experts (if they aren't already).


Step 1: Configuring Spam Experts

Add the Domain in Spam Experts

  1. Log in to the Spam Experts control panel as an administrator.
  2. Click on General > Add Domain.
  3. Enter the domain name and click Continue.
  4. Enter the correct Destination route(s) for G Suite - see G Suite Destination Server Address to find out the G Suite destination server addresses you can use.
  5. Click Add.

Check your Domain can Communicate with the G Suite Mail Servers

To ensure Spam Experts can talk to the G Suite servers you have just added, carry out a Protection status check in Spam Experts:

  1. In the Admin Level Control Panel, select General > Domains Overview to display all your domains.
  2. Click on the dropdown alongside the domain you want to check, and select Protection status to check the routes you have set:

Set the Outgoing User

  1. Click on the newly added domain in the General > Domains Overview page to open the Domain Level Control Panel for that domain.
  2. Select Outgoing > Manage users and click on the Authenticating Domain tab in the Add a user section.
  3. The domain name is already entered in the Domain field.
  4. Enter any password in the Password field (the password is not important in the G Suite setup as it is not used).
  5. Click and hold the Add button and select Add and configure.
  6. The Outgoing User Settings page is displayed.
  7. Ensure the Re-authentication permitted option is ticked.
  8. Click Save.

Automatically Discover Senders

You may want to configure the system to make sure all the mailboxes are filtered (you may want to do this as catch-all is disabled).

  1. In the Domain Level Control Panel, select General > Mailboxes Configuration.
  2. In the Configuration tab, in the Incoming panel, ensure Automatically discover senders is ticked.
