IMPORTANT: For the best experience with Hoxhunt, Proofpoint strongly recommends allowing Hoxhunt to send training emails directly to your mail server. This would allow Hoxhunt's emails to bypass Proofpoint and its link scanning, and prevent potentially skewed simulation results (auto-fails) caused by Proofpoint.

If you decide to allowlist Hoxhunt in Proofpoint instead, please note that Proofpoint may still quarantine a small amount of Hoxhunt's training emails.

Please complete every step below that matches your Proofpoint setup.
