Mem with straight gag
A friend showed me this mezuzah and said he was advised by a credible magiah that this mezuzah was pasul. I saw these pencil markings on it. I noted the mem of matar has the gag touching "too much" but mishnat hasofer says bediavad (even if the gag is a complete straight line) this can be fixed in a tefillin and mezuzah. Does anyone know of any source which would hold this mem is pasul?
