+ (nb: this is the same fix as in Exim 4.80.1)
+
+JH/11 Add A= logging on delivery lines, and a client_set_id option on
+ authenticators.
+
+JH/12 Add optional authenticated_sender logging to A= and a log_selector
+ for control.
+
+PP/12 Unbreak server_set_id for NTLM/SPA auth, broken by 4.80 PP/29.
+
+PP/13 Dovecot auth: log better reason to rejectlog if Dovecot did not
+ advertise SMTP AUTH mechanism to us, instead of a generic
+ protocol violation error. Also, make Exim more robust to bad
+ data from the Dovecot auth socket.
+
+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.
+
+JH/13 Add $router_name and $transport_name variables. Bugzilla 308.

+PP/15 Define SIOCGIFCONF_GIVES_ADDR for GNU Hurd.
+ Bug detection, analysis and fix by Samuel Thibault.
+ Bugzilla 1331, Debian bug #698092.

+SC/01 Update eximstats to watch out for senders sending 'HELO [IpAddr]'
+
+JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
+ Server implementation by Todd Lyons, client by JH.
+ Only enabled when compiled with EXPERIMENTAL_PRDR. A new
+ config variable "prdr_enable" controls whether the server
+ advertises the facility. If the client requests PRDR a new
+ acl_data_smtp_prdr ACL is called once for each recipient, after
+ the body content is received and before the acl_smtp_data ACL.
+ The client is controlled by bolth of: a hosts_try_prdr option
+ on the smtp transport, and the server advertisement.
+ Default client logging of deliveries and rejections involving
+ PRDR are flagged with the string "PRDR".
+
+PP/16 Fix problems caused by timeouts during quit ACLs trying to double
+ fclose(). Diagnosis by Todd Lyons.
+
+PP/17 Update configure.default to handle IPv6 localhost better.
+ Patch by Alain Williams (plus minor tweaks).
+ Bugzilla 880.
+
+PP/18 OpenSSL made graceful with empty tls_verify_certificates setting.
+ This is now consistent with GnuTLS, and is now documented: the
+ previous undocumented portable approach to treating the option as
+ unset was to force an expansion failure. That still works, and
+ an empty string is now equivalent.
+
+PP/19 Renamed DNSSEC-enabling option to "dns_dnssec_ok", to make it
+ clearer that Exim is using the DO (DNSSEC OK) EDNS0 resolver flag,
+ not performing validation itself.
+
+PP/20 Added force_command boolean option to pipe transport.
+ Patch from Nick Koston, of cPanel Inc.
+
+JH/15 AUTH support on callouts (and hence cutthrough-deliveries).
+ Bugzilla 321, 823.
+
+TF/04 Added udpsend ACL modifer and hexquote expansion operator

+

+
+TL/09 Add expansion variable $authenticated_fail_id to keep track of

+TL/10 Bugzilla 1375 - Prevent TLS rebinding in ldap. Patch provided by
+ Alexander Miroch.
+
+TL/11 Bugzilla 1382 - Option ldap_require_cert overrides start_tls
+ ldap library initialization, allowing self-signed CA's to be
+ used. Also properly sets require_cert option later in code by
+ using NULL (global ldap config) instead of ldap handle (per

+
+TL/12 Enhanced documentation in the ratelimit.pl script provided in

+ renamed to Transport Post Delivery Action by Jeremy Harris, as
+ EXPERIMENTAL_TPDA.
+
+TL/14 Bugzilla 1217 - Redis lookup support has been added. It is only enabled
