Sorry...I misread the last log message. You and Tony are of course correct.


Yet the original question was why Exim gives up on the message quickly and
sends a bounce. Quite possibly there are more log entries which we haven't
been shown. (For example, one of the receiving hosts saying OK, that's
enough quick retries...go away [5xx error] when the queue runner tries again
in as little as 15 minutes.)

That's what I said.

I was then (probably foolishly) suggesting that for this receiving domain
there is no point in doing that, since all the hosts are going to send back
the 4xx response. The only harm in doing it is wasted resources on both
ends (the receiving end is seemingly willing to waste them, in that it does
greylisting and has its MX and A records set up as they are).
