@@ -22,6 +22,24 @@ JH/04 Add variables $arc_domains, $arc_oldest_pass for ARC verify.  Fix the
       report of oldest_pass in ${authres } in consequence, and separate out
       some descriptions of reasons for verification fail.
 
+JH/05 Bug 2273: Cutthrough delivery left a window where the received messsage
+      files in the spool were present and unlocked.  A queue-runner could spot
+      them, resulting in a duplicate delivery.  Fix that by doing the unlock
+      after the unlink.  Investigation by Tim Stewart.  Take the opportunity to
+      add more error-checking on spoolfile handling while that code is being
+      messed with.

+PP/01 Refuse to open a spool data file (*-D) if it's a symlink.
+      No known attacks, no CVE, this is defensive hardening.

+JH/06 Bug 2275: The MIME ACL unlocked the received message files early, and
+      a queue-runner could start a delivery while other operations were ongoing.
+      Cutthrough delivery was a common victim, resulting in duplicate delivery.
+      Found and investigated by Tim Stewart.  Fix by using the open message data
+      file handle rather than opening another, and not locally closing it (which
+      releases a lock) for that case, while creating the temporary .eml format
+      file for the MIME ACL.  Also applies to "regex" and "spam" ACL conditions.
