We also have the SCL set to 7. Just use zen.spamhsus.org. Use SpamBayes on Outlook. Can't recall when last I saw a spam in my Inbox.. The drawback to SpamBayes is that it requires about 2 weeks' worth of training before it stops pretty much anything the user conceives as spam and only occasionally will one slip through, in my experience.

To save money our company elected to rely on Exchange's native SPAM filtering on the Exchange Edge servers. However, now we are getting complaints about the high level of SPAM getting through to users. One user is getting as many as 100 SPAM emails a day.and of course he is a VIP. He does not want to change his email address. But he does want us to "fix" this problem without spending money. We are considering blocking Asian and Eastern European domains, as we don't do business with those parts of the world. We also use free Real Time Black Lists (remember, can't spend money), Sender ID check, and the open proxy test. Sadly, when reviewing a lot of the SPAM our user has received we have found way too many SCL's of 0 for emails that are obviously SPAM. Oh, and lowering the SCL to 6 is also not an option, and it doesn't look like it would make much of a difference anyway. Can anyone think of anything we have missed? Is there a way to tweak the native anti-spam filtering to make it work better? Or is this as good as it gets?
