Low-energy results from measurements of leptonic dipole moments are used to derive constraints on the CP-violating phases of the dimensionful parameters of the minimal supersymmetric extension of the standard model (MSSM). We use these (known) bounds to investigate the impact of these phases on CP-even cross sections at high-energy e^+e^- and e^-e^- colliders. To that end we define two measures of the significance with which the existence of non--vanishing phases could be deduced from the measurements of these cross sections. We find that highly significant evidence for deviations from the CP-conserving MSSM could be obtained at the next e^+e^- collider even if the electric dipole moment of the electron is very small or zero. We also analyze a CP-odd final state polarization, which can be large when two different charginos or neutralinos are produced. Finally, we study correlations between the phase--sensitive observables.
