Improve mail logging

Summary

Currently JIRA Service Desk Mail Logging is internal to JIRA and it is difficult to capture this information into log files for further analysis. This can make it difficult for our users and Support to identify problems with the JIRA Service Desk Mail handler.

Expected Results

A log file that can be configured for verbosity should exist that shows details of the ServiceDesk and details of it handling mail both inbound, and out-bound.

Actual Results

You need to use the web interface to review the mail log for JIRA Service Desk.

Notes

• Steps to access the JIRA Service Desk Mail log can be accessed from: Managing the email channel It would be great to improve that so we can enable more output to the logs when necessary. Similar to the Incoming Mail in JIRA's Handlers.
• It would be great as well if there is a way to filter the status that is shown on the log from the UI. Meaning we could just filter what is "Failed" or "Success".
