Tools for mail investigation
Delivery activity in one view
Review successful, failed, deferred and rejected deliveries. Traffic timelines and peer charts help you inspect changes over time and delivery outcomes.
Address and server flows
ADDRESS FLOW connects sender and recipient email addresses. MAIL FLOW shows Postfix and actual destination servers. Hover for details.
Historical logs and SSH LIVE monitoring
Load downloaded Postfix logs and narrow results by start time and search. Configure an SSH connection to continuously monitor logs on your server.
Country statistics and a world map
Explore country access shares and delivery volumes. Lines and particles show traffic direction on the world map. Country labels include registration and domain-based estimates.
Queues, domains and DKIM
Inspect mail queue entries, destination analysis for registered domains and recorded DKIM processing. Queue actions and Fail2ban integration depend on server permissions and configuration.
A dashboard that fits your workflow
Show or hide panels, drag them to new positions, resize them and save your layout. Switch the app interface between Japanese and English.
Two flows, two perspectives

Before you start
Can I visualize historical log files?
Yes. Open saved Postfix plain-text logs in the LogGraphic desktop app to analyze delivery outcomes, view address and server flows, and replay events along the timeline. File analysis does not require an SSH connection to the server.
Does apt update upgrade the application?
No. It refreshes the package index. Then run sudo apt install --only-upgrade loggraphic and restart the app.
Can I launch the GUI over a normal SSH connection?
A GUI needs a display. Start it in the Kali desktop session or use a configured display-forwarding environment.
Does a country label identify the exact server location?
No. Country labels may come from registration information or country-code domains. They do not guarantee the physical location of an IP address.
