How to stop reports from being emailed from the server?

We have a production and also a development server where I work. They both pretty much contain the same data, but the problem is someone has enabled the emailing of reports on the development server so everyone is getting double reports.

One being emailed from the production server and one being emailed from the development server.

Is there a way or a service I can stop on the development box so the reports don't get emailed out?
