I'm not sure I have any pointers yet, I'm still on Debian Lenny and its patched exim 4.69.
I will face the same issues your describing soon so I'm also interested in what might be the smoothest solution.
I think Martin is right that the 2 different config file setup is one way to do it, think that have always been an option as far as I know.
But I think most people would prefer a 1 file solution, as we both run with currently.
So question is if anybody is going to come up with a fancy way to do that.
If not I guess you can always fall back on the 2 file solution.
Hoping to hear more about this soon.
