  We present a model where Majorana neutrino mass terms are forbidden by the
flavor symmetry group Delta(27). Neutrinos are Dirac fermions and their masses
arise in the same way as that of the charged fermions, due to very small Yukawa
couplings. The model fits current neutrino oscillation data and correlates the
octant of the atmospheric angle with the magnitude of the lightest neutrino
mass, with maximal mixing excluded for any neutrino mass
