[Exim] Per-user and To-dependent SMARTHOST/AUTH config neede…

Hello folks,

I am looking for a configuration for my fresh exim-4.21 which sets
the SMARTHOST depending on the user and/or to-address.
I found multiple user configurations, but no one handles
to-addresses. The other problem is, that that configurations were
very old, and did not work with my version...

Does anyone have a link for me?


TIA,
Tom
