I don't want to use MX records. We set up a relay server for a customer.
This relay is the only MX record for this domain. We have a manualroute
router for this customer where route_data is set in a mysql db. Now the
customer's DNS setup was broken and the host didn't resolve. Then exim
denied all incoming mails for this domain with 451 temporary rejected.
Now I search for a solution for this:

- I'd like to add more than one server in route_data for the case that
one of them fails. I tried that with : seperated entries but exim always
only uses the first one.

- I'd like that exim accepts the mail even when the server in route_data
is not resolvable. I added host_find_failed = defer to the router but
exim still rejects the mail with 451.
