Hello, I have always had problems with hotmail sending emails from my VPSes direct to Junk Folder, even with Reverse DNS of my IPs correctly configured. About 1 or 2 weeks ago CPanel added the function called Email Authentication which allows you to set the SPF record and DomainKeys. I have enabled it and waited 24 hours for the DNS propagation. Now me and my clients can send emails to hotmail directly to inbox folder. I don't know if it will work for you but it worked to me and at least 5 domains that i tested. Just wanted to share this since i have seen that a lot of people here have this kind of problems.
