Currently we are using the default value of 7, but I am very concerned with the number of false positives. E.g we get a lot of false positives from our ebay account, even after 'training'. Hence I am reluctant to simply reject at server level and instead have set up filters on the mail clients. This is a real pain. Systems like Mail Foundry (and others!) at least package up the SPAM and send them in a mail once per day + we never once got a false positive in 2+ years.
This is consuming a lot of time and effort when I feel there are more hassel-free solutions around that should be considered.
