We consider the case of very low reheating scenarios (TRH∼(MeV)) with a better calculation of the production of the relic neutrino background (with three-flavor oscillations). At 95% confidence level, a lower bound on the reheating temperature TRH>4.1 MeV is obtained from Big Bang Nucleosynthesis, while TRH>4.3 MeV from Planck data for very light (∑mi=0.06 eV) neutrinos. If neutrino masses are allowed to vary, Planck data yield TRH>4.7 MeV, the most stringent bound on the reheating temperature to date. Neutrino masses as large as 1 eV are possible for very low reheating temperatures
