ORF is a GREAT product with GREAT support. At at time in the industry when you can never get a real person to answer a support question, the folks at Vamsoft responded quickly and personally to help me close up some gapping holes in my spam filtering process. They took the usefulness of ORF to a new level and I'm truly grateful for their product and assistance.
