What is Postfix?
Postfix is a powerful open-source mail transfer agent (MTA) that routes and delivers email on Unix-like operating systems. It’s designed for reliability, security, and high performance. Postfix manages message queues; handles incoming and outgoing emails; and provides tools for filtering, logging, and access control—making it ideal for managing email traffic in both small and large environments.
Monitor the health and performance of your Postfix email servers
Track and analyze key queue metrics like total messages in mailq, active, and deferred queues to ensure smooth email flow and reduce delivery delays.
Gain visibility into bounce, corrupt, hold, and incoming email queues to troubleshoot issues faster and maintain the reliability of your email server.
Set threshold-based alerts for sudden spikes in deferred or bounce messages so you can take immediate action and avoid email delivery disruptions.
Visualize all your Postfix metrics on custom dashboards, alongside data from your broader infrastructure, to stay informed and manage email server performance proactively.
