Is there some way I could get an instant spam rating report or something for an e-mail? One of my clients is in content sales, and it wasn't long before we found out that "sale" was a huge spam trigger. So, are there any online free tools that could give an instant report, or how I could go about starting off for CREATING one?
Wasn't quite sure what you're after. Did you want something to filter spam when your client download their emails onto their pc?
