This section provides guidelines to help you determine why your FortiMail unit is behaving unexpectedly. It includes general troubleshooting methods and specific troubleshooting tips using both the command line interface (CLI) and the web UI. Each troubleshooting item describes both the problem and the solution.
Some CLI commands provide troubleshooting information not available through the web UI. The web UI is better suited for viewing large amounts of information on screen, reading logs and archives, and viewing status through the dashboard.
For additional information, see “Best practices and fine tuning” on page 697.
