Turning off SuSEconfig

Hello all: I'd like to be able to configure postfix by hand on my 8.1 box. It appears however that some component of Suse is mucking with my changes. I recall that you can tell suse not to be concerned with configuring certain things. However, I can't seem to find any such setting anywhere in Yast2 for Postfix. How do I tell SuSE to stop messing with my Postfix config? -Thanks.
