In this technote ClearPass using Gmail as Messaging Server, I'll walk through using Gmail as a messaging server in ClearPass, particularly useful in lab environments where you're testing solutions that require email integration.
Here are some solutions that require email integrations.
• Trigger email delivery of credentials after MPSK registration.
• Guest access with sponsor approval
• Schedule automated delivery of Insight reports via email
• Authentication failure notification via email
• Use post-authentication enforcement profiles to trigger email notifications based on defined policy conditions.
• Email notifications for client quarantine events.
• Send email notifications when ClearPass detects a security event through its integration with an EDR/XDR platform (e.g., CrowdStrike).

In the next technote I will cover the enforcement profiles that can send email notifications.
Hope you'll find it useful and as always please send through your feedback for improvement.
