Aha, I see what you mean. The host_find_failed option (for example) is
tested at the router phase and if it fails, it never reaches the
transport for that router. I suppose it would be technically possible to
implement something like a "smart" version of the fallback_hosts router
option, but then I suppose based on what's next that you would refuse to
consider doing that.

I disagree with that, but since I don't have time to learn the skills to
mess with the code, I'll have to live with it.
Exim is great anyway, and I want you to know that I appreciate your work
as well as your taking the time to discuss things like this.
