Change log file for Exim from version 4.21
-------------------------------------------
+This document describes *changes* to previous versions, that might
+affect Exim's operation, with an unchanged configuration file. For new
+options, and new features, see the NewStuff file next to this ChangeLog.
+
+Exim version 4.88
+-----------------
+JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
+ supports it and a size is available (ie. the sending peer gave us one).
+
+JH/02 The obsolete acl condition "demime" is removed (finally, after ten
+ years of being deprecated). The replacements are the ACLs
+ acl_smtp_mime and acl_not_smtp_mime.
+
+JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
+ a downgraded non-dane trust-anchor for the TLS connection (CA-style)
+ or even an in-clear connection were permitted. Now, if the host lookup
+ was dnssec and dane was requested then the host is only used if the
+ TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
+ MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
+ if one fails this test.
+ This means that a poorly-configured remote DNS will make it incommunicado;
+ but it protects against a DNS-interception attack on it.
+
+JH/04 Bug 1810: make continued-use of an open smtp transport connection
+ non-noisy when a race steals the message being considered.
+
+JH/05 If main configuration option tls_certificate is unset, generate a
+ self-signed certificate for inbound TLS connections.
+
+JH/06 Bug 165: hide more cases of password exposure - this time in expansions
+ in rewrites and routers.
+
+JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
+ and logged a warning sing 4.83; now they are a configuration file error.
+
+JH/08 Bug 1836: Fix crash in VRFY handling when handed an unqualified name
+ (lacking @domain). Apply the same qualification processing as RCPT.
+
+JH/09 Bug 1804: Avoid writing msglog files when in -bh or -bhc mode.
+
+JH/10 Support ${sha256:} applied to a string (as well as the previous
+ certificate).
+
+JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
+ a cutthrough deliver is pending, as we always want to make a connection.
+ This also avoids re-routing the message when later placing the cutthrough
+ connection after a verify cache hit.
+ Do not update it with the verify result either.
+
+JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
+ when routing results in more than one destination address.
+
+JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
+ signing (which inhibits the cutthrough capability). Previously only
+ the presence of an option was tested; now an expansion evaluating as
+ empty is permissible (obviously it should depend only on data available
+ when the cutthrough connection is made).
+
+JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
+ the relevant preceding SMTP command did not note the pipelining mode.
+
+JH/15 Fix counting of empty lines in $body_linecount and $message_linecount.
+ Previously they were not counted.
+
+JH/16 DANE: treat a TLSA lookup response having all non-TLSA RRs, the same
+ as one having no matching records. Previously we deferred the message
+ that needed the lookup.
+
+JH/17 Fakereject: previously logged as a norml message arrival "<="; now
+ distinguished as "(=".
+
+JH/18 Bug 1867: make the fail_defer_domains option on a dnslookup router work
+ for missing MX records. Previously it only worked for missing A records.
+
+JH/19 Bug 1850: support Radius libraries that return REJECT_RC.
+
+JH/20 Bug 1872: Ensure that acl_smtp_notquit is run when the connection drops
+ after the data-go-ahead and data-ack. Patch from Jason Betts.
+
+JH/21 Bug 1846: Send DMARC forensic reports for reject and quaratine results,
+ even for a "none" policy. Patch from Tony Meyer.
+
+JH/22 Fix continued use of a connection for further deliveries. If a port was
+ specified by a router, it must also match for the delivery to be
+ compatible.
+
+JH/23 Bug 1874: fix continued use of a connection for further deliveries.
+ When one of the recipients of a message was unsuitable for the connection
+ (has no matching addresses), we lost track of needing to mark it
+ deferred. As a result mail would be lost.
+
+JH/24 Bug 1832: Log EHLO response on getting conn-close response for HELO.
+
+JH/25 Decoding ACL controls is now done using a binary search; the source code
+ takes up less space and should be simpler to maintain. Merge the ACL
+ condition decode tables also, with similar effect.
+
+JH/26 Fix problem with one_time used on a redirect router which returned the
+ parent address unchanged. A retry would see the parent address marked as
+ delivered, so not attempt the (identical) child. As a result mail would
+ be lost.
+
+JH/27 Fix a possible security hole, wherein a process operating with the Exim
+ UID can gain a root shell. Credit to http://www.halfdog.net/ for
+ discovery and writeup. Ubuntu bug 1580454; no bug raised against Exim
+ itself :(
+
+JH/28 Enable {spool,log} filesystem space and inode checks as default.
+ Main config options check_{log,spool}_{inodes,space} are now
+ 100 inodes, 10MB unless set otherwise in the configuration.
+
+JH/29 Fix the connection_reject log selector to apply to the connect ACL.
+ Previously it only applied to the main-section connection policy
+ options.
+
+JH/30 Bug 1897: fix callouts connection fallback from TLS to cleartext.
+
+PP/01 Changed default Diffie-Hellman parameters to be Exim-specific, created
+ by me. Added RFC7919 DH primes as an alternative.
+
+PP/02 Unbreak build via pkg-config with new hash support when crypto headers
+ are not in the system include path.
+
+JH/31 Fix longstanding bug with aborted TLS server connection handling. Under
+ GnuTLS, when a session startup failed (eg because the client disconnected)
+ Exim did stdio operations after fclose. This was exposed by a recent
+ change which nulled out the file handle after the fclose.
+
+JH/32 Bug 1909: Fix OCSP proof verification for cases where the proof is
+ signed directly by the cert-signing cert, rather than an intermediate
+ OCSP-signing cert. This is the model used by LetsEncrypt.
+
+JH/33 Bug 1914: Ensure socket is nonblocking before draining after SMTP QUIT.
+
+HS/01 Fix leak in verify callout under GnuTLS, about 3MB per recipient on
+ an incoming connection.
+
+HS/02 Bug 1802: Do not half-close the connection after sending a request
+ to rspamd.
+
+
+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.
+
+JH/07 Bug 1678: Always record an interface option value, if set, as part of a
+ retry record, even if constant. There may be multiple transports with
+ different interface settings and the retry behaviour needs to be kept
+ distinct.
+
+JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.
+
+JH/09 Bug 1700: ignore space & tab embedded in base64 during decode.
+
+JH/10 Bug 840: fix log_defer_output option of pipe transport
+
+JH/11 Bug 830: use same host for all RCPTS of a message, even under
+ hosts_randomize. This matters a lot when combined with mua_wrapper.
+
+JH/12 Bug 1706: percent and underbar characters are no longer escaped by the
+ ${quote_pgsql:<string>} operator.
+
+JH/13 Bug 1708: avoid misaligned access in cached lookup.
+
+JH/14 Change header file name for freeradius-client. Relevant if compiling
+ with Radius support; from the Gentoo tree and checked under Fedora.
+
+JH/15 Bug 1712: Introduce $prdr_requested flag variable
+
+JH/16 Bug 1714: Permit an empty string as expansion result for transport
+ option transport_filter, meaning no filtering.
+
+JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
+
+JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
+ defaults to "*" (all hosts). The variable is now available when not built
+ with TLS, default unset, mainly to enable keeping the testuite sane.
+ If a server certificate is not supplied (via tls_certificate) an error is
+ logged, and clients will find TLS connections fail on startup. Presumably
+ they will retry in-clear.
+ Packagers of Exim are strongly encouraged to create a server certificate
+ at installation time.
+
+HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
+ with the $config_file variable.
+
+JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
+ in transport context, after the attempt, and per-recipient. The latter type
+ is per host attempted. The event data is the error message, and the errno
+ information encodes the lookup type (A vs. MX) used for the (first) host,
+ and the trailing two digits of the smtp 4xx reponse.
+
+GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
+ to write to mainlog (or rejectlog, paniclog) in the window between file
+ creation and permissions/ownership being changed. Particularly affects
+ installations where exicyclog is run as root, rather than exim user;
+ result is that the running daemon panics and dies.
+
+JH/20 Bug 1701: For MySQL lookups, support MySQL config file option group names.
+
+JH/21 Bug 1720: Add support for priority groups and weighted-random proxy
+ selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
+ "pri" and "weight". Note that the previous implicit priority given by the
+ list order is no longer honoured.
+
+JH/22 Bugs 963, 1721: Fix some corner cases in message body canonicalisation
+ for DKIM processing.
+
+JH/23 Move SOCKS5 support from Experimental to mainline, enabled for a build
+ by defining SUPPORT_SOCKS.
+
+JH/26 Move PROXY support from Experimental to mainline, enabled for a build
+ by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
+ is renamed to hosts_proxy, and the proxy_{host,target}_{address,port}.
+ variables are renamed to proxy_{local,external}_{address,port}.
+
+JH/27 Move Internationalisation support from Experimental to mainline, enabled
+ for a build by defining SUPPORT_I18N
+
+JH/28 Bug 1745: Fix redis lookups to handle (quoted) spaces embedded in parts
+ of the query string, and make ${quote_redis:} do that quoting.
+
+JH/29 Move Events support from Experimental to mainline, enabled by default
+ and removable for a build by defining DISABLE_EVENT.
+
+JH/30 Updated DANE implementation code to current from Viktor Dukhovni.
+
+JH/31 Fix bug with hosts_connection_nolog and named-lists which were wrongly
+ cached by the daemon.
+
+JH/32 Move Redis support from Experimental to mainline, enabled for a build
+ by defining LOOKUP_REDIS. The libhiredis library is required.
+
+JH/33 Bug 1748: Permit ACL dnslists= condition in non-smtp ACLs if explicit
+ keys are given for lookup.
+
+JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
+ support, by using OpenSSL or GnuTLS library ones. This means DKIM is
+ only supported when built with TLS support. The PolarSSL SHA routines
+ are still used when the TLS library is too old for convenient support.
+
+JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
+ openssl_options), for security. OpenSSL forces this from version 1.1.0
+ server-side so match that on older versions.
+
+JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
+ allocation for $value could be released as the expansion processing
+ concluded, but leaving the global pointer active for it.
+
+JH/37 Bug 1769: Permit a VRFY ACL to override the default 252 response,
+ and to use the domains and local_parts ACL conditions.
+
+JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
+ incorrectly not doubled on cutthrough transmission, hence seen as a
+ body-termination at the receiving system - resulting in truncated mails.
+ Commonly the sender saw a TCP-level error, and retransmitted the message
+ via the normal store-and-forward channel. This could result in duplicates
+ received - but deduplicating mailstores were liable to retain only the
+ initial truncated version.
+
+JH/39 Bug 1781: Fix use of DKIM private-keys having trailing '=' in the base-64.
+
+JH/40 Fix crash in queryprogram router when compiled with EXPERIMENTAL_SRS.
+
+JH/41 Bug 1792: Fix selection of headers to sign for DKIM: bottom-up. While
+ we're in there, support oversigning also; bug 1309.
+
+JH/42 Bug 1796: Fix error logged on a malware scanner connection failure.
+
+HS/04 Add support for keep_environment and add_environment options.
+
+JH/43 Tidy coding issues detected by gcc --fsanitize=undefined. Some remain;
+ either intentional arithmetic overflow during PRNG, or testing config-
+ induced overflows.
+
+JH/44 Bug 1800: The combination of a -bhc commandline option and cutthrough
+ delivery resulted in actual delivery. Cancel cutthrough before DATA
+ stage.
+
+JH/45 Fix cutthrough, when connection not opened by verify and target hard-
+ rejects a recipient: pass the reject to the originator.
+
+JH/46 Multiple issues raised by Coverity. Some were obvious or plausible bugs.
+ Many were false-positives and ignorable, but it's worth fixing the
+ former class.
+
+JH/47 Fix build on HP-UX and older Solaris, which need (un)setenv now also
+ for the new environment-manipulation done at startup. Move the routines
+ from being local to tls.c to being global via the os.c file.
+
+JH/48 Bug 1807: Fix ${extract } for the numeric/3-string case. While preparsing
+ an extract embedded as result-arg for a map, the first arg for extract
+ is unavailable so we cannot tell if this is a numbered or keyed
+ extraction. Accept either.
+
+
+
+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.
+
+HS/03 Add perl_taintmode main config option
+
+
+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
is requested by default, modifiable by smtp transport option
hosts_request_ocsp.
-JH/22 Expansion operators ${md5:string} and ${sha1::string} can now
+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/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.
