Hi,

This isn't possible, the thing you can do with whitelists are described below:

Harmony Email & Collaboration allows to define exceptions for Anti-Phishing, Anti-Malware, and DLP.

• To view how to define Allow-List and Block-List for Anti-Malware, see Anti-Malware Exceptions.

• To view how to define Allow-List for DLP, see DLP Allow-List.
