An exact solution of a two-dimensional RSOS model of wetting at a corrugated (periodic) wall is found using transfer matrix techniques. In contrast to mean-field analysis of the same problem, the wetting transition remains second order and occurs at a lower temperature than that of the planar system. A comparison with numerical studies and other analytical approaches is made.
