I have tracked this down, and you are right. There is a bug. The
circumstances are:

1. The address is routed using the lookuphost router, but there are no
MX records for the domain - it is routed using A records.

AND

2. The fallback hosts are specified on the smtp transport, not on the
router.

There is a (pretty trivial) patch below against Exim 3.33 that fixes
this. Unfortunately, it won't work against 3.32 (which you are using)
because other things have changed in the same module. However, if you
make the same change by hand it will work.

Alternatively, a workaround is to move your fallback_hosts setting from
the transport to the router.
