TrustedSource and other sites are used to answer questions such as – is someone sending spam that looks like it is coming from my domain, called spoofing? Has my Web site been compromised recently? Do I have an open relay email server that I don’t know about? The Internet is a nasty place, and the idea that a service can be watching globally for exploits is a good one.
