Microsoft doesn't blacklist your ip but some range of ip .....
you can try to contact microsoft through the snds service.

Hi,

I recently bought a Kimsufi Dedicated Server, and my problem is that I can't send mails to Microsoft mail, like hotmail, windowslive or outlook.
I can send mails without any problem to other hosts! I think the IP is blacklisted, but I don't know why.

This is the error what I get:
Code:
Reporting-MTA: dns; server.konorbi.us
X-Postfix-Queue-ID: 6204E401D16
X-Postfix-Sender: rfc822; konorbi@konorbi.us

Final-Recipient: rfc822; something@hotmail.hu
Action: failed
Status: 5.0.0
Remote-MTA: dns; mx2.hotmail.com
Diagnostic-Code: smtp; 550 SC-001 (COL0-MC3-F15) Unfortunately, messages from
    94.23.x.x weren't sent. Please contact your Internet service provider
    since part of their network is on our block list. You can also refer your
    provider to http://mail.live.com/mail/troubleshooting.aspx#errors.
I have to contact Microsoft or you can fix this issue?

Best Regards,
