Turning off spam notifications

Recently, my WordPress installation has started emailing me whenever I get a spam comment. This is driving me insane, but I can’t figure out how to turn it off. I don’t think I changed any settings, so it probably changed when I updated my installation to a new version. Is there anyway to change this setting either in WordPress or Akismet so that I am only notified only when I receive a non-spam comment?

Thanks
