We're in the process of transferring our email provider, and removing our reliance on Virgin Media. It's a free service to us, granted, but only borrowed as part of a consumer package paid for by a private sponsor, which we can't rely on forever.
For now, freeitstafford@virginmedia.com emails will still find their way to us, but we will be gradually renewing our services to instead use freeitstafford@engineer.com, if you could begin to update your own records to suit :)
