Change log file for Exim from version 4.21
-------------------------------------------
+
+Exim version 4.87
+-----------------
+JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
+ and 3.4.4 - once the server is enabled to respond to an OCSP request
+ it does even when not requested, resulting in a stapling non-aware
+ client dropping the TLS connection.
+
+TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
+ support variable-length bit vectors. No functional change.
+
+TF/02 Improve the consistency of logging incoming and outgoing interfaces.
+ The I= interface field on outgoing lines is now after the H= remote
+ host field, same as incoming lines. There is a separate
+ outgoing_interface log selector which allows you to disable the
+ outgoing I= field.
+
+JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
+ If not running log_selector +smtp_connection the mainlog would be held
+ open indefinitely after a "too many connections" event, including to a
+ deleted file after a log rotate. Leave the per net connection logging
+ leaving it open for efficiency as that will be quickly detected by the
+ check on the next write.
+
+HS/01 Bug 1671: Fix post transport crash.
+ Processing the wait-<transport> messages could crash the delivery
+ process if the message IDs didn't exist for some reason. When
+ using 'split_spool_directory=yes' the construction of the spool
+ file name failed already, exposing the same netto behaviour.
+
+JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
+ mime_regex ACL conditions.
+
+JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
+ to DSN fail messages (bounces): remote IP, remote greeting, remote response
+ to HELO, local diagnostic string.
+
+JH/05 Downgrade message for a TLS-certificate-based authentication fail from
+ log line to debug. Even when configured with a tls authenticator many
+ client connections are expected to not authenticate in this way, so
+ an authenticate fail is not an error.
+
+HS/02 Add the Exim version string to the process info. This way exiwhat
+ gives some more detail about the running daemon.
+
+JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
+ matter for fast-change records such as DNSBLs.
+
+
+Exim version 4.86
+-----------------
+JH/01 Bug 1545: The smtp transport option "retry_include_ip_address" is now
+ expanded.
+
+JH/02 The smtp transport option "multi_domain" is now expanded.
+
+JH/03 The smtp transport now requests PRDR by default, if the server offers
+ it.
+
+JH/04 Certificate name checking on server certificates, when exim is a client,
+ is now done by default. The transport option tls_verify_cert_hostnames
+ can be used to disable this per-host. The build option
+ EXPERIMENTAL_CERTNAMES is withdrawn.
+
+JH/05 The value of the tls_verify_certificates smtp transport and main options
+ default to the word "system" to access the system default CA bundle.
+ For GnuTLS, only version 3.0.20 or later.
+
+JH/06 Verification of the server certificate for a TLS connection is now tried
+ (but not required) by default. The verification status is now logged by
+ default, for both outbound TLS and client-certificate supplying inbound
+ TLS connections
+
+JH/07 Changed the default rfc1413 lookup settings to disable calls. Few
+ sites use this now.
+
+JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
+ Status Notification (bounce) messages are now MIME format per RFC 3464.
+ Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
+ under the control of the dsn_advertise_hosts option, and routers may
+ have a dsn_lasthop option.
+
+JH/09 A timeout of 2 minutes is now applied to all malware scanner types by
+ default, modifiable by a malware= option. The list separator for
+ the options can now be changed in the usual way. Bug 68.
+
+JH/10 The smtp_receive_timeout main option is now expanded before use.
+
+JH/11 The incoming_interface log option now also enables logging of the
+ local interface on delivery outgoing connections.
+
+JH/12 The cutthrough-routing facility now supports multi-recipient mails,
+ if the interface and destination host and port all match.
+
+JH/13 Bug 344: The verify = reverse_host_lookup ACL condition now accepts a
+ /defer_ok option.
+
+JH/14 Bug 1573: The spam= ACL condition now additionally supports Rspamd.
+ Patch from Andrew Lewis.
+
+JH/15 Bug 670: The spamd_address main option (for the spam= ACL condition)
+ now supports optional time-restrictions, weighting, and priority
+ modifiers per server. Patch originally by <rommer@active.by>.
+
+JH/16 The spamd_address main option now supports a mixed list of local
+ and remote servers. Remote servers can be IPv6 addresses, and
+ specify a port-range.
+
+JH/17 Bug 68: The spamd_address main option now supports an optional
+ timeout value per server.
+
+JH/18 Bug 1581: Router and transport options headers_add/remove can
+ now have the list separator specified.
+
+JH/19 Bug 392: spamd_address, and clamd av_scanner, now support retry
+ option values.
+
+JH/20 Bug 1571: Ensure that $tls_in_peerdn is set, when verification fails
+ under OpenSSL.
+
+JH/21 Support for the A6 type of dns record is withdrawn.
+
+JH/22 Bug 608: The result of a QUIT or not-QUIT toplevel ACL now matters
+ rather than the verbs used.
+
+JH/23 Bug 1572: Increase limit on SMTP confirmation message copy size
+ from 255 to 1024 chars.
+
+JH/24 Verification callouts now attempt to use TLS by default.
+
+HS/01 DNSSEC options (dnssec_require_domains, dnssec_request_domains)
+ are generic router options now. The defaults didn't change.
+
+JH/25 Bug 466: Add RFC2322 support for MIME attachment filenames.
+ Original patch from Alexander Shikoff, worked over by JH.
+
+HS/02 Bug 1575: exigrep falls back to autodetection of compressed
+ files if ZCAT_COMMAND is not executable.
+
+JH/26 Bug 1539: Add timout/retry options on dnsdb lookups.
+
+JH/27 Bug 286: Support SOA lookup in dnsdb lookups.
+
+JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
+ Normally benign, it bites when the pair was led to by a CNAME;
+ modern usage is to not canoicalize the domain to a CNAME target
+ (and we were inconsistent anyway for A-only vs AAAA+A).
+
+JH/29 Bug 1632: Removed the word "rejected" from line logged for ACL discards.
+
+JH/30 Check the forward DNS lookup for DNSSEC, in addition to the reverse,
+ when evaluating $sender_host_dnssec.
+
+JH/31 Check the HELO verification lookup for DNSSEC, adding new
+ $sender_helo_dnssec variable.
+
+JH/32 Bug 1397: Enable ECDHE on OpenSSL, just the NIST P-256 curve.
+
+JH/33 Bug 1346: Note MAIL cmd seen in -bS batch, to avoid smtp_no_mail log.
+
+JH/34 Bug 1648: Fix a memory leak seen with "mailq" and large queues.
+
+JH/35 Bug 1642: Fix support of $spam_ variables at delivery time. Was
+ documented as working, but never had. Support all but $spam_report.
+
+JH/36 Bug 1659: Guard checking of input smtp commands again pseudo-command
+ added for tls authenticator.
+
+
+Exim version 4.85
+-----------------
+TL/01 When running the test suite, the README says that variables such as
+ no_msglog_check are global and can be placed anywhere in a specific
+ test's script, however it was observed that placement needed to be near
+ the beginning for it to behave that way. Changed the runtest perl
+ script to read through the entire script once to detect and set these
+ variables, reset to the beginning of the script, and then run through
+ the script parsing/test process like normal.
+
+TL/02 The BSD's have an arc4random API. One of the functions to induce
+ adding randomness was arc4random_stir(), but it has been removed in
+ OpenBSD 5.5. Detect this OpenBSD version and skip calling this
+ function when detected.
+
+JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
+ cause callback expansion.
+
+TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
+ syntax errors in an expansion can be treated as a string instead of
+ logging or causing an error, due to the internal use of bool_lax
+ instead of bool when processing it.
+
+JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
+ server certificates when making smtp deliveries.
+
+JH/03 Support secondary-separator specifier for MX, SRV, TLSA lookups.
+
+JH/04 Add ${sort {list}{condition}{extractor}} expansion item.
+
+TL/04 Bugzilla 1216: Add -M (related messages) option to exigrep.
+
+TL/05 GitHub Issue 18: Adjust logic testing for true/false in redis lookups.
+ Merged patch from Sebastian Wiedenroth.
+
+JH/05 Fix results-pipe from transport process. Several recipients, combined
+ with certificate use, exposed issues where response data items split
+ over buffer boundaries were not parsed properly. This eventually
+ resulted in duplicates being sent. This issue only became common enough
+ to notice due to the introduction of conection certificate information,
+ the item size being so much larger. Found and fixed by Wolfgang Breyha.
+
+JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
+ size buffer was used, resulting in syntax errors when an expansion
+ exceeded it.
+
+JH/07 Add support for directories of certificates when compiled with a GnuTLS
+ version 3.3.6 or later.
+
+JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
+ is EXPERIMENTAL_EVENT, the main-configuration and transport options
+ both become "event_action", the variables become $event_name, $event_data
+ and $event_defer_errno. There is a new variable $verify_mode, usable in
+ routers, transports and related events. The tls:cert event is now also
+ raised for inbound connections, if the main configuration event_action
+ option is defined.
+
+TL/06 In test suite, disable OCSP for old versions of openssl which contained
+ early OCSP support, but no stapling (appears to be less than 1.0.0).
+
+JH/09 When compiled with OpenSSL and EXPERIMENTAL_CERTNAMES, the checks on
+ server certificate names available under the smtp transport option
+ "tls_verify_cert_hostname" now do not permit multi-component wildcard
+ matches.
+
+JH/10 Time-related extraction expansions from certificates now use the main
+ option "timezone" setting for output formatting, and are consistent
+ between OpenSSL and GnuTLS compilations. Bug 1541.
+
+JH/11 Fix a crash in mime ACL when meeting a zero-length, quoted or RFC2047-
+ encoded parameter in the incoming message. Bug 1558.
+
+JH/12 Bug 1527: Autogrow buffer used in reading spool files. Since they now
+ include certificate info, eximon was claiming there were spoolfile
+ syntax errors.
+
+JH/13 Bug 1521: Fix ldap lookup for single-attr request, multiple-attr return.
+
+JH/14 Log delivery-related information more consistently, using the sequence
+ "H=<name> [<ip>]" wherever possible.
+
+TL/07 Bug 1547: Omit RFCs from release. Draft and RFCs have licenses which
+ are problematic for Debian distribution, omit them from the release
+ tarball.
+
+JH/15 Updates and fixes to the EXPERIMENTAL_DSN feature.
+
+JH/16 Fix string representation of time values on 64bit time_t anchitectures.
+ Bug 1561.
+
+JH/17 Fix a null-indirection in certextract expansions when a nondefault
+ output list separator was used.
+
+
+Exim version 4.84
+-----------------
+TL/01 Bugzilla 1506: Re-add a 'return NULL' to silence complaints from static
+ checkers that were complaining about end of non-void function with no
+ return.
+
+JH/01 Bug 1513: Fix parsing of quoted parameter values in MIME headers.
+ This was a regression intruduced in 4.83 by another bugfix.
+
+JH/02 Fix broken compilation when EXPERIMENTAL_DSN is enabled.
+
+TL/02 Bug 1509: Fix exipick for enhanced spoolfile specification used when
+ EXPERIMENTAL_DSN is enabled. Fix from Wolfgang Breyha.
+
+
+Exim version 4.83
+-----------------
+
+TF/01 Correctly close the server side of TLS when forking for delivery.
+
+ When a message was received over SMTP with TLS, Exim failed to clear up
+ the incoming connection properly after forking off the child process to
+ deliver the message. In some situations the subsequent outgoing
+ delivery connection happened to have the same fd number as the incoming
+ connection previously had. Exim would try to use TLS and fail, logging
+ a "Bad file descriptor" error.
+
+TF/02 Portability fix for building lookup modules on Solaris when the xpg4
+ utilities have not been installed.
+
+JH/01 Fix memory-handling in use of acl as a conditional; avoid free of
+ temporary space as the ACL may create new global variables.
+
+TL/01 LDAP support uses per connection or global context settings, depending
+ upon the detected version of the libraries at build time.
+
+TL/02 Experimental Proxy Protocol support: allows a proxied SMTP connection
+ to extract and use the src ip:port in logging and expansions as if it
+ were a direct connection from the outside internet. PPv2 support was
+ updated based on HAProxy spec change in May 2014.
+
+JH/02 Add ${listextract {number}{list}{success}{fail}}.
+
+TL/03 Bugzilla 1433: Fix DMARC SEGV with specific From header contents.
+ Properly escape header and check for NULL return.
+
+PP/01 Continue incomplete 4.82 PP/19 by fixing docs too: use dns_dnssec_ok
+ not dns_use_dnssec.
+
+JH/03 Bugzilla 1157: support log_selector smtp_confirmation for lmtp.
+
+TL/04 Add verify = header_names_ascii check to reject email with non-ASCII
+ characters in header names, implemented as a verify condition.
+ Contributed by Michael Fischer v. Mollard.
+
+TL/05 Rename SPF condition results err_perm and err_temp to standardized
+ results permerror and temperror. Previous values are deprecated but
+ still accepted. In a future release, err_perm and err_temp will be
+ completely removed, which will be a backward incompatibility if the
+ ACL tests for either of these two old results. Patch contributed by
+ user bes-internal on the mailing list.
+
+JH/04 Add ${utf8clean:} operator. Contributed by Alex Rau.
+
+JH/05 Bugzilla 305: Log incoming-TLS details on rejects, subject to log
+ selectors, in both main and reject logs.
+
+JH/06 Log outbound-TLS and port details, subject to log selectors, for a
+ failed delivery.
+
+JH/07 Add malware type "sock" for talking to simple daemon.
+
+JH/08 Bugzilla 1371: Add tls_{,try_}verify_hosts to smtp transport.
+
+JH/09 Bugzilla 1431: Support (with limitations) headers_add/headers_remove in
+ routers/transports under cutthrough routing.
+
+JH/10 Bugzilla 1005: ACL "condition =" should accept values which are negative
+ numbers. Touch up "bool" conditional to keep the same definition.
+
+TL/06 Remove duplicated language in spec file from 4.82 TL/16.
+
+JH/11 Add dnsdb tlsa lookup. From Todd Lyons.
+
+JH/12 Expand items in router/transport headers_add or headers_remove lists
+ individually rather than the list as a whole. Bug 1452.
+
+ Required for reasonable handling of multiple headers_ options when
+ they may be empty; requires that headers_remove items with embedded
+ colons must have them doubled (or the list-separator changed).
+
+TL/07 Add new dmarc expansion variable $dmarc_domain_policy to directly
+ view the policy declared in the DMARC record. Currently, $dmarc_status
+ is a combined value of both the record presence and the result of the
+ analysis.
+
+JH/13 Fix handling of $tls_cipher et.al. in (non-verify) transport. Bug 1455.
+
+JH/14 New options dnssec_request_domains, dnssec_require_domains on the
+ dnslookup router and the smtp transport (applying to the forward
+ lookup).
+
+TL/08 Bugzilla 1453: New LDAP "SERVERS=" option allows admin to override list
+ of ldap servers used for a specific lookup. Patch provided by Heiko
+ Schlichting.
+
+JH/18 New options dnssec_lax, dnssec_strict on dnsdb lookups.
+ New variable $lookup_dnssec_authenticated for observability.
+
+TL/09 Bugzilla 609: Add -C option to exiqgrep, specify which exim.conf to use.
+ Patch submitted by Lars Timman.
+
+JH/19 EXPERIMENTAL_OCSP support under GnuTLS. Bug 1459.
+
+TL/10 Bugzilla 1454: New -oMm option to pass message reference to Exim.
+ Requires trusted mode and valid format message id, aborts otherwise.
+ Patch contributed by Heiko Schlichting.
+
+JH/20 New expansion variables tls_(in,out)_(our,peer)cert, and expansion item
+ certextract with support for various fields. Bug 1358.
+
+JH/21 Observability of OCSP via variables tls_(in,out)_ocsp. Stapling
+ is requested by default, modifiable by smtp transport option
+ hosts_request_ocsp.
+
+JH/22 Expansion operators ${md5:string} and ${sha1:string} can now
+ operate on certificate variables to give certificate fingerprints
+ Also new ${sha256:cert_variable}.
+
+JH/23 The PRDR feature is moved from being Experimental into the mainline.
+
+TL/11 Bug 1119: fix memory allocation in string_printing2(). Patch from
+ Christian Aistleitner.
+
+JH/24 The OCSP stapling feature is moved from Experimental into the mainline.
+
+TL/12 Bug 1444: Fix improper \r\n sequence handling when writing spool
+ file. Patch from Wolfgang Breyha.
+
+JH/25 Expand the coverage of the delivery $host and $host_address to
+ client authenticators run in verify callout. Bug 1476.
+
+JH/26 Port service names are now accepted for tls_on_connect_ports, to
+ align with daemon_smtp_ports. Bug 72.
+
+TF/03 Fix udpsend. The ip_connectedsocket() function's socket type
+ support and error reporting did not work properly.
+
+TL/13 Bug 1495: Exiqgrep check if -C config file specified on cli exists
+ and is readable. Patch from Andrew Colin Kissa.
+
+TL/14 Enhance documentation of ${run expansion and how it parses the
+ commandline after expansion, particularly in the case when an
+ unquoted variable expansion results in an empty value.
+
+JH/27 The TLS SNI feature was broken in 4.82. Fix it.
+
+PP/02 Fix internal collision of T_APL on systems which support RFC3123
+ by renaming away from it. Addresses GH issue 15, reported by
+ Jasper Wallace.
+
+JH/28 Fix parsing of MIME headers for parameters with quoted semicolons.
+
+TL/15 SECURITY: prevent double expansion in math comparison functions
+ (can expand unsanitized data). Not remotely exploitable.
+ CVE-2014-2972
+
+
Exim version 4.82
-----------------
TL/05 Bugzilla 1285 - Spec omission, fix docbook errors for spec.txt creation.
+TL/06 Add Experimental DMARC support using libopendmarc libraries.
+
+TL/07 Fix an out of order global option causing a segfault. Reported to dev
+ mailing list by by Dmitry Isaikin.
+
JH/01 Bugzilla 1201 & 304 - New cutthrough-delivery feature, with TLS support.
JH/02 Support "G" suffix to numbers in ${if comparisons.
JH/03 Add expansion operators ${listnamed:name} and ${listcount:string}
-PP/09 Add gnutls_enable_pkcs11 option.
+PP/09 Add gnutls_allow_auto_pkcs11 option (was originally called
+ gnutls_enable_pkcs11, but renamed to more accurately indicate its
+ function.
PP/10 Let Linux makefile inherit CFLAGS/CFLAGS_DYNAMIC.
Pulled from Debian 30_dontoverridecflags.dpatch by Andreas Metzler.
PP/11 SECURITY: protect DKIM DNS decoding from remote exploit.
CVE-2012-5671
+ (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
+
+PP/21 Fix eximon continuous updating with timestamped log-files.
+ Broken in a format-string cleanup in 4.80, missed when I repaired the
+ other false fix of the same issue.
+ Report and fix from Heiko Schlichting.
+ Bugzilla 1363.
+
+PP/22 Guard LDAP TLS usage against Solaris LDAP variant.
+ Report from Prashanth Katuri.
+
+PP/23 Support safari_ecdhe_ecdsa_bug for openssl_options.
+ It's SecureTransport, so affects any MacOS clients which use the
+ system-integrated TLS libraries, including email clients.
+
+PP/24 Fix segfault from trying to fprintf() to a NULL stdio FILE* if
+ using a MIME ACL for non-SMTP local injection.
+ Report and assistance in diagnosis by Warren Baker.
+
+TL/08 Adjust exiqgrep to be case-insensitive for sender/receiver.
+
+JH/16 Fix comparisons for 64b. Bugzilla 1385.
+
+TL/09 Add expansion variable $authenticated_fail_id to keep track of
+ last id that failed so it may be referenced in subsequent ACL's.
+
+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
+ session). Bug diagnosis and testing by alxgomz.
+
+TL/12 Enhanced documentation in the ratelimit.pl script provided in
+ the src/util/ subdirectory.
+
+TL/13 Bug 1031 - Imported transport SQL logging patch from Axel Rau
+ 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
+ when Exim is compiled with EXPERIMENTAL_REDIS. A new config variable
+ redis_servers = needs to be configured which will be used by the redis
+ lookup. Patch from Warren Baker, of The Packet Hub.
+
+TL/15 Fix exiqsumm summary for corner case. Patch provided by Richard Hall.
+
+TL/16 Bugzilla 1289 - Clarify host/ip processing when have errors looking up a
+ hostname or reverse DNS when processing a host list. Used suggestions
+ from multiple comments on this bug.
+
