'X' means that we've converted the legacy prop ( that was either 1 or 0/non-existant ) to ESN -- I somehow must have missed this use, cause the original code is from before my patch. There's no actual way to set opt_getselfemail anyomore.

This can probably be a separate fix in this case given it was apparently there before, but this `$recieve_own_comment` will not behave as expected.
