How to configure 'skiplisting' under Office 365

If you wish to activate Office365's anti-spam functionalities upstream of your Zerospam filtering service, skiplisting is for you. This is an Office365 feature that allows you to keep the IP address as well as the original sender information during email security analysis. This adds an extra layer of security to your messages.

Skiplisting is an advanced functionality available under Office365. We recommend not to activate this option without fully understanding the stakes.

It is important to understand that the activation of skiplisting involves the maintenance of 2 anti-spam solutions at the same time, which requires additional time and resources from your organization.

If you want to activate skiplisting, please refer to the detailed documentation on Microsoft's website.
