I have a few employees that get 30-40 spam e-mails per day. I have IMF turned on and the threshold for junk mail is 4, delete is 7. The problem is that the stuff that makes it to the inbox is rated 0 or 1 or 2. So I have viagra e-mails that are looked at as good mail and just forwards it to the inbox.
Is there any better way to filter this? I currently use IMF with IMF Companion so that I can use a whitelist. This is on a exchange 2003 box.
