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- 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:} 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 private-keys having trailing '=' in the base-64. + + + +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 . + +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= []" 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.
