+22. The hosts_max_try_hardlimit option (default 50) is added to the smtp
+    transport. Exim will never try more than this number of IP addresses; if it
+    hits this limit and they are all timed out, the message is bounced, even
+    though not all IP addresses may have been tried. Compare hosts_max_try,
+    which is a "soft" limit, because Exim will exceed it when hosts time out.
+    The new limit is a protection against lunatic DNS configurations with
