These days, I would be *surprised* if most mail-accepting domains *did* have a postmaster address - and even more so if they actually had someone monitoring it, or otherwise ensuring that mail sent to it didn't just get dropped into the bit bucket. RFC / spec compliance can easily be, and I suspect usually is, disregarded in this regard.
