Microsoft don't look at individual IP's, they look at IP-span from the 
same network provider, so if one or more IP-numbers have sent too much 
spam in a time frame, then the whole span will be blocked.

The owner of the IP address (usually your hosting company) has to 
request that your IP will be cleared. Can nowadays be done from: 
https://sendersupport.olc.protection.outlook.com/snds/

For looking at the status of your IP and the IP-span you belong to, check:
http://www.uceprotect.net/en/rblcheck.php
If UCE Protect flags your span to send out a lot of spam, then you will 
be more than likely blocked at microsoft's mail service.

You could use a smarter host to send to microsoft, you should talk a bit 
with your hosting company, so that you can use their mail server as a 
smarter host.

Not sure how to configure this in postfix.

Yeah, but will not help you due of spf record for domains, will just 
make you look more like a spammer.
