PMTA Alerts by Younes Kountate

PMTA Alerts is a lightweight Firefox extension that monitors PowerMTA server statistics and provides instant browser notifications when important conditions are detected.


• Last Minute OUT Alerts — Get notified when the monitored server's Last Minute OUT reaches zero.

• OUT Decrease Alerts — Optionally receive an alert whenever the Last Minute OUT value decreases.

• Queue Recipient Alerts — Monitor specific queues and receive a notification when a queue reaches its configured recipient limit.

• NTFY Phone Notifications — Send PMTA alerts to your phone through NTFY by configuring your NTFY topic in the extension settings.

• Custom Monitoring Interval — Choose how frequently the PMTA page is checked.

• Multiple Queue Monitoring — Add and configure multiple queues with individual recipient limits.

• Easy Settings — Configure alert modes, monitored queues, limits, monitoring interval, and NTFY notifications from one settings page.


Open each PMTA server in its own browser tab. PMTA Alerts monitors the server page and automatically checks the configured statistics at the selected interval.

When a configured alert condition is detected, the extension displays a Firefox notification. If an NTFY topic is configured, the alert can also be delivered to your phone.

PMTA Alerts is designed for simple, fast monitoring without requiring a separate dashboard.
