Can you provide a build log with debug mode enabled?

slide_o_mix can you point me to documentation that would show me how to do debug logging.  I have tried https://www.jenkins.io/doc/book/system-administration/viewing-logs/#logs-in-jenkins using hudson.plugins.emailext as the logger, but it did not capture anything.  I do not know what I am doing to get the log that you want to view.  Thanks!

This is a special setting you can turn on in the "Manage Jenkins > System Configuration" setup. Under Extended Email Publishing there should be a checkbox for "debug mode". If you turn that on and then run a build, it should add a bunch of additional information to the build log. Please remember to sanitize the build log before posting (remove actual email addresses, etc).

slide_o_mix Thank you.  I figured it would be something simple.  I have just kicked a job manually and will attached a sanitized build log after it completes. 

slide_o_mix I think I see what is happening in the log.  I have multiple triggers setup under Success.  Recipient List, Developer and Culprits.  In the log it only processes the first trigger, Recipient List and never appears to processes the following Developer and Culprits trigger.  Possibly looping logic?  Attached debug_log.txt

The odd thing is that the project setup has not changed much recently, just the global configuration. The log file will definitely help.

In the spots where is says things like parsing and sending, do those have actual real email addresses that have been sanitized?

Need more information, please reopen if this is still and issue and provide a build log.
