Unfortunately, the world is not perfect. There are a lot of mail servers not RFC compliance around. If you are agressive on your ACLs, good messages will be dropped. Statistic filters like osbf-lua evolve, if spam behavior change, it can be trained with a false-negative, new spam attack will be blocked. End users have diferent behavior on mail use, statistics filters can evolve and adapt. On my concern, it´s necessary use more than one layer of spam protection nowadays. Exim ACL´s with statistics filters is a very good choice. The problem with statistics filters that it's not a out-of-box solution, you have to feed it with a good number of messages (over 2,500) to get 99% of accuracy, but the final result is great.
