How to access ExceptionNotifier variables

Question

How can I access ExceptionNotifier variables such as sender_address or exception_recipients in my custom mailer class? Since ExceptionNotifier is implemented as Rack middleware, I'm not sure how to go about it.

Please explain what you want to do in practice. There are several alternatives, depending on what you want to accomplish. — Simone Carletti, May 12 '11 at 08:59
@Simone: I'd like to send exception notifications when an exception happens in a delayed_job worker. In order to do that, it looks like I have to write my own mailer, so I'd like to get `sender_address` and `exception_recipients` from the ExceptionNotifier configuration. — Alex Korban, May 12 '11 at 09:21

I still don't know how to access the ExceptionNotifier variables, so the workaround I decided on is to add these variables to Rails config instead, and use them to configure both ExceptionNotifier and my custom mailer:

config.exception_subject_prefix = "[App Error] "
config.exception_sender = "support@example.com"
config.exception_recipients = %w{support@example.com}

config.middleware.use "::ExceptionNotifier",
                      :email_prefix => config.exception_subject_prefix,
                      :sender_address => %{ #{config.exception_sender} },
                      :exception_recipients => config.exception_recipients

The config variables can be accessed elsewhere as Rails.configuration.exception_sender and so on.
