Not easy within the structure of the Exim code. As far as I know, the
only way to check that you can bind a socket to an interface is to
attempt to do so.
If you want to check in a router, you can write a program or script of
your own to do the check, and then call it using ${run ... That would
allow you to run a particular router conditionally.
