How to unblock e-mail domains

Mail from my organization (ons.org) is being blocked by default for Hotmail, but not for Outlook.com addresses for some reason.

If I add the address to the accounts safe sender list or contacts the e-mails will go through. The problem is we run an online school, and some people register with hotmail.com addresses. When we send them their course access instructions, they don't get it because hotmail is blocking us by default. On the mail logs Hotmail accepts the e-mail and reports it's queued for sending. We don't get an NDR telling us the e-mail was rejected, but it doesn't go to the user's junk mail or inbox either. It just gets held somewhere. 

Is there a form I can fill out, number I can call? There doesn't seem to be a lot of support for this kind of thing.

Thanks,

Will
