+TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
+
+      When a queue runner is handling a message, Exim first routes the
+      recipient addresses, during which it prunes them based on the retry
+      hints database. After that it attempts to deliver the message to
+      any remaining recipients. It then updates the hints database using
+      the retry rules.
+
+      So if a recipient address works intermittently, it can get repeatedly
+      deferred at routing time. The retry hints record remains fresh so the
+      address never reaches the final cutoff time.
+
+      This is a fairly common occurrence when a user is bumping up against
+      their storage quota. Exim had some logic in its local delivery code
+      to deal with this. However it did not apply to per-recipient defers
+      in remote deliveries, e.g. over LMTP to a separate IMAP message store.
+
+      This change adds a proper retry rule check during routing so that the
+      final cutoff time is checked against the message's age. We only do
+      this check if there is an address retry record and there is not a
+      domain retry record; this implies that previous attempts to handle
+      the address had the retry_use_local_parts option turned on. We use
+      this as an approximation for the destination being like a local
+      delivery, as in LMTP.
+
+      I suspect this new check makes the old local delivery cutoff check
+      redundant, but I have not verified this so I left the code in place.
+
+TF/02 Correct gecos expansion when From: is a prefix of the username.
+
+      Test 0254 submits a message to Exim with the header
+
+        Resent-From: f
+
+      When I ran the test suite under the user fanf2, Exim expanded
+      the header to contain my full name, whereas it should have added
+      a Resent-Sender: header. It erroneously treats any prefix of the
+      username as equal to the username.
+
+      This change corrects that bug.
+
+GF/01 DCC debug and logging tidyup
+      Error conditions log to paniclog rather than rejectlog.
+      Debug lines prefixed by "DCC: " to remove any ambiguity.

+TF/03 Avoid unnecessary rebuilds of lookup-related code.
+
+PP/14 Fix OCSP reinitialisation in SNI handling for Exim/TLS as server.
+      Bug spotted by Jeremy Harris; was flawed since initial commit.
+      Would have resulted in OCSP responses post-SNI triggering an Exim
+      NULL dereference and crash.
