Automatic Address adding in entourage

It seems that my entourage is adding incoming emails automatically to the address book which seems to defeat SpamSieve !!
any thoughts how to turn the automatic address adding off?
thanks

I’m not aware of such a feature in Entourage. I think it would only do that if you had created a rule in Entourage using the “Add sender to address book” action. Also, this would only affect SpamSieve you if clicked the Load button to load the new addresses from Entourage into SpamSieve. So it seems unlikely to me that this is causing SpamSieve accuracy problems for you. Does SpamSieve’s log actually say that it’s letting spam messages through because of the Entourage address book?
