Setting up an Inbound Gateway for Portal IPs
This section describes how to set up an inbound gateway for the Portal IPs. Setting up the inbound gateway should prevent warning banners from appearing on your phishing emails in G Suite.
After logging in to your Google Admin Console, go to Apps > G Suite > Advanced Settings. In the General Settings section, click on your top-level organization (usually your primary domain) on the left. Scroll down and click on Inbound gateway (under the Spam section) and match your settings as the following:
In the Message Tagging section check the 'Message is considered spam if the following header regexp matches' checkbox. Enter a long string of characters that is unlikely to be sent in an email in the 'Regexp' field, e.g. '9ECDA0116EB508285106053A58CBBFF6EA88A652'. Select the 'Message is spam if regexp matches' radio button, and check the 'Disable Gmail spam evaluation on mail from this gateway; only use header value' checkbox.
Save the settings for the Inbound gateway.
Click 'CONFIGURE' in the Spam section.
Give the new spam list a short description. Check the 'Bypass spam filters for messages received from addresses or domains within these approved senders lists' checkbox. If no lists are used yet, click the 'Use existing or create a new one' link, enter a name for the list, and then click 'CREATE'.
After creating the list, click the 'Edit' link in the new list's row.
Add the domains you intend to use in phishing tests to the new list. After entering a domain click 'SAVE'. If you wish to add additional domains, click the + icon.
Once you have completed the new spam rule, click 'ADD SETTING' located in the lower right-hand corner of the window.
Allow time for the propagation of these rules.
