Can the SMTP Service on Windows 2003 Server be setup to work with one or more IP blacklist providers? If not, what about Windows 2003 Server in general?

IIS's internal SMTP component can't do such fancy things; that's the only mail engine in Windows Server 2003, and it's not up to this job.
I'm afraid you'll have to get a mail server in order to do this kind of filtering; if you want to stick with a Microsoft solution, Exchange 2007 can use blacklist providers.
