I use every thirty minutes, but I'm running two instances of exim one
with more frequent runs, then I use delivery_event and write a redis
record when I see a trigger phrase in the response.

The redis record holds an ip list excluding the ip address of the server
and is used as ignore_target_hosts in a router to side-track the next
delivery attempt of that, and similar messages to the slow instance.
