try an email address like yahoo or gmail for your to line. That might help you.
On my problem I think I have another clue if the youremail is from someone on my safe sender it will go through to my hotmail account, but this is not a good solution because the majority of my contact form people are not going to be on my safe list. So I think the problem is with my hotmail settings but I can't figure it out. I took out all my blocked users and it still is filtering the unknown users.
