You need to look at the reason you're blacklisted, they usually provide a reason when your mail is rejected and you should contact Hotmail about the problem. You should has a reverse DNS, SPF & DKIM records (and use them) and also make sure you're not on any RBLs, that would be a start.

There are several comments in there, how to know what?,

a) you would have asked your ISP for a reverse DNS, check it with 'host your.ip.add.ress'

b) you would have set-up external DNS SPF & DKIM records (and installed some form of DKIM milter on your server).

c) you can check if you're on any RBL: +rbl +check - Yahoo! Search Results
