Currently email sent from our servers is being blocked by Hotmail (which is also msn.com) because part of our hosting vendor's network is on the Hotmail blacklist. We have opened a ticket with Rackspace to have this resolved.
In the meantime, the emails from the job board are not making it through to hotmail.com or msn.com email addresses. Please continue to submit requests for passwords through email@example.com while we work to get this fixed.
We are very sorry for this inconvenience.
