The order of testing is documented in section 3.9. On looking at that, I
see that in fact require_files is tested before condition, and senders
is tested before both of them.

If you want to test for the existence of a file before "senders", you
can write

senders = ${if exists{/some/file}{your senders list}{never@???}}

If the file does not exist, you will end up with

senders = never@???

and, assuming that no sender can ever be that address, the router will
be skipped.
