Spontaneous CP violation is realized in SUSY via an extended spurion formalism in the exact limit and a model with intermediate-scale breaking along pseudo-flat directions stabilized by soft terms and non-perturbative gauge effects, predicting light scalars.

abstract
We show that spontaneous breaking of discrete or continuous symmetries does not necessarily imply either symmetry restoration or the thermal production of defects at high temperature (at least up to $T \sim M_{Planck}$). This may imply that there is no domain wall problem. As an example we show how this applies to the Peccei-Quinn scenario.

Exploring the Landscape of Spontaneous CP Violation in Supersymmetric Theories
