+Exim 3.20 has a feature that allows a large mailing of a single message to
+be sent to many different relays. This is useful for mailing lists, as it
+allows the message to be relayed to multiple machines, in groups of 100
+addresses, for final delivery.
+
+The router lists a host, but it does not really use that host. Instead the
+list of host machines in the transport are used in a random order, thus
+getting a reasonable coverage and compensating for delivery machines and
+networks that are down.
