+JH/08 Bug 2598: Fix verify ACL condition. The options for the condition are
+ expanded; previously using tainted values was rejected. Fix by using
+ dynamically-created buffers.
+
+JH/10 Bug 2603: Fix coding of string copying to only evaluate arguments once.
+ Previously a macro used one argument twice; when called with the
+ argument as an expression having side-effects, incorrect operation
+ resulted. Use an inlineable function.
+
+JH/11 Bug 2604: Fix request to cutthrough-deliver when a connection is already
+ held open for a verify callout. Previously this wan not accounted for
+ and a corrupt onward SMTP conversation resulted.
