Problem Definition

By having Service Desk Emails setting enabled we can't have incoming mail log and Debug mode for incoming mail.
The workaround is to create a dummy incoming mail handler with same details a Service Desk mail setting to be able to debug the incoming mail.

Solution

By enabling Service Desk mail setting the mail handler should be shown at incoming mail handler page(refer to JSD-1831) so it helps to have debug mode for the Service Desk too.

Workarounds

1. Type ‘g’ + ‘g’ + start typing ‘logging and profiling’
   1. Navigate to the ‘Default Loggers’ section
   2. Click ‘Configure logging level for another package’
   3. Type com.atlassian.mail.incoming and set the logging level to debug
   4. Click ‘Add'
   5. Then replicate the issue again
   6. Mark the log with "replication starts here"
   7. Replicate the problem ( Send a test mail to the inbox and make sure the email is processed )
   8. Mark the log again with "replication ends here"
   9. Generate a new Support Zip and attach it here
2. In order to enable debug mode for service desk mail and have the basic logs, a dummy mail handler with same details should be created in JIRA incoming mail.
