I think you'd said that you'd narrowed it down to the safety relief, but if there is any doubt... You can put the tip of a cold, stainless-steel knife directly beside or over the possible escape points. The steam will condense quite visibly on cold stainless. No sense replacing the wrong part, nor replacing a valve if it's only leaking at the fitting or somesuch.

If it only happens during warm up it is likely NOT the safety valve but the vacuum breaker valve, and a slight hissing just before the pressure starts to rise in the boiler is normal. That is what it is supposed to do. It is venting air as the water begins to heat up.
