+PH/10 There is a new ACL control called "suppress_local_fixups". This applies
+ to locally submitted (non TCP/IP) messages, and is the complement of
+ "control = submission". It disables the fixups that are normally applied
+ to locally-submitted messages. Specifically:
+
+ (a) Any Sender: header line is left alone (in this respect, it's a
+ dynamic version of local_sender_retain).
+
+ (b) No Message-ID:, From:, or Date: headers are added.
+
+ (c) There is no check that From: corresponds to the actual sender.
+
+ This feature may be useful when a remotely-originated message is
+ accepted, passed to some scanning program, and then re-submitted for
+ delivery. It means that all four possibilities can now be specified:
+
+ (1) Locally submitted, fixups applies: the default.
+ (2) Locally submitted, no fixups applied: use control =
+ suppress_local_fixups.
+ (3) Remotely submitted, no fixups applied: the default.
+ (4) Remotely submitted, fixups applied: use control = submission.
+
+PH/11 There is a new log selector, "unknown_in_list", which provokes a log
+ entry when the result of a list match is failure because a DNS lookup
+ failed.
