How to Enable Extended Logging in Exim

The extended Exim logs in a cPanel server are invaluable for troubleshooting Exim issues, as they provide additional logging information to the exim_mainlog (/var/log/exim_mainlog) file, aiding in identifying the source and sender of messages.

Follow the steps to enable the extended logging in WHM-

1. Log in to WHM.
2. Select the “Service Configuration” tool and click on the “Exim Configuration Manager” sub-option.
   
   
3. Select the “Advanced Editor” tab.
   
4. Edit the Exim configuration file exim.conf by modifying the log_selector option, which controls the amount of information Exim writes to its log files.The following options are recommended-

   log_selector = +addressrewrite +all_parents +arguments +subject
   

5. Scroll down and click “Save” at the bottom of the page. You can now keep an eye on the Exim log at /var/log/exim_mainlog for any additional details.
