We consider a supersymmetric SU(5) model where two neutrino masses are obtained via a mixed type I+III seesaw mechanism induced by the component fields of a single SU(5) adjoint. We have analyzed the phenomenology of the model paying particular attention to flavour violating processes and dark matter relic density. We have found that, for a seesaw scale larger than $10^{12\div 13}$~GeV, Br$(\mu\to e \gamma)$ is in the reach of the MEG experiment in sizable regions of the parameter space. On the other side, current bounds on it force Br$(\tau \to \mu \gamma)$ to be well below the reach of forthcoming experiments, rendering thus the model disprovable if a positive signal is found. The same bounds still allow for a sizable positive contributio...
