I think I have now discovered what the problem is. The option
dns_again_means_nonexist was applying to direct DNS lookups, but not
when Exim was using gethostbyname() (or equivalent). Thinking about
this, I've decided that in fact it *should* apply in that case because
temporary errors from gethostbyname() are almost certainly in fact to be
dns problems.

This will be changed in the forthcoming 4.61 release. I don't need any
more evidence now.
