IT Problem
If you have a spam problem on exchange exchange 2010 then it may be wise to look into adding an IP Block List Provider. These providers maintain a database of ip addresses that have been flagged as sending out spam.an IP block list provider can be setup in the emc or via powershell. This article shows how to setup and ip blocklist provider in powershell. For the Emc, read on.
These are the providers that I recommend as they are free and well maintained.
