I have been instructed to implement a SPAM filtering solution for our Exchange 2000 environment. I am currently looking at a couple of products and I am leaning towards GFI Mail Essentials 8. My ideal solution would be one similar to YAHOO's spam filtering. I would want to send suspected spam to a mailbox on that particular user. Then they could reply to me stating if it is incorrect so that I could adjust the rules or add the sender to a whitelist. Does anyone know of a product that can do this? I haven't seen it, but I figured that I would ask others. Any other thoughts or solutions would be welcomed as well.
