[exim] lookup of host fails, exim gives up

I am having my first few days of experiences with exim. It seems to be
incredible in the amount of configuration you can do. Much more than the
windows email server we have currently.

I am trying to setup some manualroute.

If I supply a couple hosts, like maybe:

invalid.example.com:mx2.example.com

Obviously the first one is not valid. From the debugging I can see exim
says lookup of host "invalid.example.com" failed in myrouter router

So the question is why does exim not just move on?

I also saw similar symptoms when using dnslookup. In that case what I saw
was if there was no reply from the server with the highest priority MX
record, exim would stop trying.

How do I get it to push on and try other hosts?
