Your product is as close to bullet proof as I have ever seen. My install of ORF has been running for over 6 months without a reboot or modification and is still doing exactly what is expected. When I consider that we have processed 37 million pieces of mail without a single user complaint or whitelist request in that time, I can't help but be impressed! Add to that the outstanding customer support/service and you get the best anti-spam solution on the market hands down.
