As of this Sunday we appear unable to send email notifications to hotmail accounts and other mail services owned by Microsoft.
I'll try to investigate the issue, but I expect it might take some time to resolve.
In the meantime, if you rely on email notifications from VF and you have another email address you can use, then I'd recommend switching.
