If using Avanan, admins may need to configure their Avanan instance to accommodate Phin IPs, URLs, and domains.

You may need to configure Microsoft 365 and/or Google Workspace so that messages from Phin can be delivered successfully. This may involve creating a mail flow rule in the Exchange admin center that will look for Phin IP addresses and add a header that lets Avanan know that the email is safe.

If you have any issues, please contact the Avanan support team.
