Change log file for Exim from version 4.21
-------------------------------------------
lack of a "<=" line in the log, and they are now listed as "not
accepted".
+PH/38 The host_find_failed option in the manualroute router can now be set
+ to "ignore", to completely ignore a host whose IP address cannot be
+ found. If all hosts are ignored, the behaviour is controlled by the new
+ host_all_ignored option.
+
Exim version 4.66

New Features in Exim
--------------------
19. The exigrep utility now has a -v option, which inverts the matching
condition.
+20. The host_find_failed option in the manualroute router can now be set to
+ "ignore". This causes it to completely ignore a host whose IP address
+ cannot be found. If all the hosts in the list are ignored, the behaviour is
+ controlled by the new host_all_ignored option, which takes the same values
+ as host_find_failed, except that it cannot be set to "ignore". Its default
+ is "defer".
+
Version 4.66
