where is the log for mail-handler

[Gerhard Urschler]

I have added two incoming mail-handlers from my imap server. one is working, the other is not working. where can I find the log file to debug the issue?

[Jack Brickey]

We don't have access to the Jira mail handler log. 

can you explain in greater detail what is going wrong? Can you share your mail handler configuration and how does it differ from the one that is working?
