We calculate the exact lowest-order collisional contribution to the polarizability of a one-component classical plasma. Both approximate analytic and numerical solutions are obtained over a wide range of frequencies and at long wavelengths, with a full taking into account of previously ignored dynamical effects in the screening. We have established a reliable standard against which plasma approximation schemes can be compared in order to assess their accuracy in the weak-coupling limit. We compare the exact solutions with those calculated in our earlier velocity-average-approximation scheme updated to take account of dynamical effects in the screening.
