yes, but we should also not send bounces... I think that presently
sender callout is used more as a anti-spam tool than anything else.
So the ability to distinguish between different type of failure would
greatly help. This issues has been raised before, I proposed an extra
flag to change the behaviour, but of course if we could return
multiple value results that would not be necessary. I had a look at
the code but realise it would take me perhaps too much time to work
out how to do it without breaking anything...
