I'm using version 3.1.4 and it has been working great in the past. Some spam would always slip through however. More recently it seems I've been getting more spam. I changed the threshold to make it more sensitive but however a good bit is still getting through. Do I need to upgrade SA or just get more rules or something else? I read up on some things and it looks like you can use a utility against a spam box to "learn" the spam and block it. Anyone familiar with this?
