The corresponding classical electrodynamics to a quantum electrodynamics with a propagator depending on restmassless photons and photons with restmass, too, is a field theory of the fourth order given by the wave‐operator □ (1− □/ k 2 ). This electrodynamics has a physical meaning only if the electro‐static potential ϕ becomes the C OULOMB potential asymptotically, and if the point‐like field sources (electrons) have monopol‐like chargedistributions: ϱ ∼ δ( r ). From these postulates results that such a classical field‐theory becomes the electrodynamics of B OPP and of P ODOLSKY . However, such a classical electrodynamics is only possible with time‐like photons, the hypothesis of space‐like photons gives contradictions to the postulates about the electro‐static field and about the monopol‐like structure of the point‐like electron‐charges.
