First, look at /var/log/maillog.  If you're sending or relaying spam, it 
will probably be pretty obvious.

Second, the listing may apply to your entire network, and could be the 
result of some other system, or it could be an old listing from a system 
which previously used your address.  If your system is secure, follow 
hotmail's process for de-listing your address.
