I'm not receiving the confirmation email, even with SPAM filtering turned off

I have tried a couple of times to log into my account. It responds with a message indicating that a confirmation email has been sent. I have tried getting the system to send it three times, without any luck. I'm not sure where it may be going. Also, what is the domain name from which the email will be sent. My email address, which has worked in the past, is jonathan.belanger@carestream.com
