+15. "Lightweight" support for Redis Cluster. Requires redis_servers list to
+ contain all the servers in the cluster, all of which must be reachable from
+ the running exim instance. If the cluster has master/slave replication, the
+ list must contain all the master and slave servers.
+
+16. Add an option to the Avast scanner interface: "pass_unscanned". This
+ allows to treat unscanned files as clean. Files may be unscanned for
+ several reasons: decompression bombs, broken archives.
