Dictionary Scores and SpamProfiler %

Hi, I am using IronMail 6.7.2 as an AntiSpam Engine. I have a confusion regarding Dictionaries updation and scoring. I want to ask that wheather the scores of individual dictionaries are being changed automatically via automatic updates . I think yes. But if scores are being changed on regular basis , will it not effect the Spam intervention in our network. Also on daily basis how many new words are updated in dictionaries . If i stop updates then what is the drawback ? Also in the SpamProfiler I have locked the confidence value. Does this mean that the confidence value (%) which I have set will never be changed ? Is it also ok or not. Kindly recommend .....

    Yes, the confidence and threshold values can change with the anti-spam updates.  It will effect the spam effectiveness - that is the point.  As the spam team follows trends they adjust the scores to be most effective wihile causing as few false positives as possible.

    Also on daily basis how many new words are updated in dictionaries . If i stop updates then what is the drawback ? Also in the SpamProfiler I have locked the confidence value. Does this mean that the confidence value (%) which I have set will never be changed ? Is it also ok or not.

    No information is published on what is added / removed from the dictionaries (that I know of).  If you stop updates you will start to see spam effectiveness drop.  Most likely slowly at first, but over time you will see larger and large quantites of messages not being detected.  Locking any setting will prevent the automatic updates from changing it.  If this is truly what you want, then it is a perfectly acceptble course of action - but be aware support may suggest you change it if you call with false positives or false negatives.
