Is your feature request related to a problem? Please describe.
When errors occur during callbacks on a production environment, with debug=False. This breaks the production and more than likely restarts the worker.

Describe the solution you'd like
When starting up the server, allow for a mailbox item like smtp to be passed in order to send error alerts with traceback messages to the identified email address. ie app.run(mail=mail, error_to=emailaddress) Then, when an error occurs, raise PreventUpdate or some other standard error message, along the lines of "IT has been notified of the error that just occurred."

Describe alternatives you've considered
Wrapping all callbacks with the try except clause where an alert is sent to my email.
