Error response if issue creation by mail fails

It would be nice to have a feedback if the creation of an issue by email fails for any reason.

Our customers doesn't have any feedback in case the issue is not created from their mail. Eg. they accidentally sent from a different email address than they regisitered in JIRA.

The best would if it could be set that:

• send a customizable email back to the sender and/or
• send a detailed mail to specified email address (eg. to Lead Developer or would be better to handle it as an Email Issue Creation Fail event which would be customizable by project wich group/person would receive a notification)
