Temat: [Exim] lack of timeout on host lookup failures
I run a few small mail servers here and when a valid user's domain's NS
is unavailable, exim tries again immediately. There doesn't seem to be
a) a limit to the number of times tried or b) some kind of timeout.

Or do I need to RTFM more diligently?

For example:-

2003-03-25 16:18:12 H=localhost.localdomain (post.tobit.co.uk) [127.0.0.1] F=<pelicans-bounces@???> temporarily rejected RCPT <polly_king25@???>: host lookup
did not complete
2003-03-25 16:18:22 H=localhost.localdomain (post.tobit.co.uk) [127.0.0.1] F=<pelicans-bounces@???> temporarily rejected RCPT <polly_king25@???>: host lookup
did not complete
2003-03-25 16:18:32 H=localhost.localdomain (post.tobit.co.uk) [127.0.0.1] F=<pelicans-bounces@???> temporarily rejected RCPT <polly_king25@???>: host lookup
did not complete
2003-03-25 16:18:42 H=localhost.localdomain (post.tobit.co.uk) [127.0.0.1] F=<pelicans-bounces@???> temporarily rejected RCPT <polly_king25@???>: host lookup
did not complete
2003-03-25 16:18:53 H=localhost.localdomain (post.tobit.co.uk) [127.0.0.1] F=<pelicans-bounces@???> temporarily rejected RCPT <polly_king25@???>: host lookup
did not complete
2003-03-25 16:19:03 H=localhost.localdomain (post.tobit.co.uk) [127.0.0.1] F=<pelicans-bounces@???> temporarily rejected RCPT <polly_king25@???>: host lookup
did not complete

Do not be fooled by the 10 second or so interval, on another one it may
retry every second or even faster.
