The email service stopped working sometime in the last few days. We've stopped receiving email notifications when somebody pushes to our repo.
This doesn't seem to be related to the repo itself (it's affecting multiple repositories). If it makes a difference, these are the repos we're using; the 'email service' is not working for either of them:
I checked my Spam box to see if the emails were mistakenly being routed there, but they're not.
