+ 6. There is a new ACL control called "debug", to enable debug logging.
+    This allows selective logging of certain incoming transactions within
+    production environments, with some care.  It takes two options, "tag"
+    and "opts"; "tag" is included in the filename of the log and "opts"
+    is used as per the -d<options> command-line option.  Examples, which
+    don't all make sense in all contexts:
+
+      control = debug
+      control = debug/tag=.$sender_host_address
+      control = debug/opts=+expand+acl
+      control = debug/tag=.$message_exim_id/opts=+expand
