We're using a Non Quoted Comment Handler to add comments to issues via email. Some of our emails to JIRA users have bounced, leaving bounce messages from "System Administrator" in the mailbox. These messages cause the handler to write warnings to the stdout log. Over time, as these messages pile up in the mailbox, these log entries cause the log to ballon to 100mb+, which eventually results in the JIRA service throwing Out of Memory exceptions. I can imagine this would only be worse if say, virus infected clients were sending messages to the JIRA mailbox in question.

Possible solution:
+ Add an option to the handler "Delete messages from unauthorized mail senders"
+ Add a sub-option: "Log message body before deletion"
