Reputation Lookup for IPs

xzap writes "ZDNet is running an article about TrustedSource.org which is a new portal that provides reputation information for IP addresses. It can be used to configure your spam filters or when deciding whether to add an unknown host to your blacklist. Dmitri Alperovitch, a research engineer at CipherTrust said "Often companies don't realize that they have zombie machines on their network that have been sending e-mail. It may be more helpful for organizations to identify which systems on their networks are sending e-mail." Users can drill down to find more information on each domain. The portal is an initiative of CipherTrust who have previously been covered on Slashdot."
