Thoroughly combine flour, salt, baking soda, baking powder, and cinnamon. Set aside.
Blend together butter and sugars. Quickly add eggs, molasses, and vanilla. Combine the flour and egg mixtures. Add oats and raisins. Scoop dough with a small cookie or ice cream scoop into balls. Chill dough balls well.
Bake for eight to 12 minutes depending on the size of the cookies. (Chocolate chips may be substituted for raisins.)
