The first two hosts accept a connection, but do not answer within 10s,
so Exim can't test whether it will accept the sender address. Therefore,
Exim will try the next host(s).

According to the documentation, Exim will also try the next hosts when
it receives a 4xx reply, but I think it would have logged that.
