The transport option tls_verify_cert_hostname + can be used to disable this per-host. The build option + EXPERIMENTAL_CERTNAMES is withdrawn. + + +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 parameter in the + incoming message. + +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 Buf 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. + + +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.

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 +----------------- + +PP/01 Add -bI: framework, and -bI:sieve for querying sieve capabilities. + +PP/02 Make -n do something, by making it not do something. + When combined with -bP, the name of an option is not output. + +PP/03 Added tls_dh_min_bits SMTP transport driver option, only honoured + by GnuTLS. + +PP/04 First step towards DNSSEC, provide $sender_host_dnssec for + $sender_host_name and config options to manage this, and basic check + routines. + +PP/05 DSCP support for outbound connections and control modifier for inbound. + +PP/06 Cyrus SASL: set local and remote IP;port properties for driver. + (Only plugin which currently uses this is kerberos4, which nobody should + be using, but we should make it available and other future plugins might + conceivably use it, even though it would break NAT; stuff *should* be + using channel bindings instead). + +PP/07 Handle "exim -L " to indicate to use syslog with tag as the process + name; added for Sendmail compatibility; requires admin caller. + Handle -G as equivalent to "control = suppress_local_fixups" (we used to + just ignore it); requires trusted caller. + Also parse but ignore: -Ac -Am -X + Bugzilla 1117. + +TL/01 Bugzilla 1258 - Refactor MAIL FROM optional args processing. + +TL/02 Add +smtp_confirmation as a default logging option. + +TL/03 Bugzilla 198 - Implement remove_header ACL modifier. + Patch by Magnus Holmgren from 2007-02-20. + +TL/04 Bugzilla 1281 - Spec typo. + Bugzilla 1283 - Spec typo. + Bugzilla 1290 - Spec grammar fixes. + +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.

Bugzilla 199. + +JH/10 Add 8bitmime log_selector, for 8bitmime status on the received line. + Pulled from Bugzilla 817 by Wolfgang Breyha. + +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.

See also change 4.74-TF/03. + +TF/03 Make the exiwhat support code safe for signals. Previously Exim might + lock up or crash if it happened to be inside a call to libc when it + got a SIGUSR1 from exiwhat. + + The SIGUSR1 handler appends the current process status to the process + log which is later printed by exiwhat. It used to use the general + purpose logging code to do this, but several functions it calls are + not safe for signals. + + The new output code in the SIGUSR1 handler is specific to the process + log, and simple enough that it's easy to inspect for signal safety. + Removing some special cases also simplifies the general logging code. + Removing the spurious timestamps from the process log simplifies + exiwhat. + +TF/04 Improved ratelimit ACL condition. + + The /noupdate option has been deprecated in favour of /readonly which + has clearer semantics. The /leaky, /strict, and /readonly update modes + are mutually exclusive. The update mode is no longer included in the + database key; it just determines when the database is updated. (This + means that when you upgrde Exim will forget old rate measurements.) + + Exim now checks that the per_* options are used with an update mode that + makes sense for the current ACL. For example, when Exim is processing a + message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify + per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you + must specify per_mail/readonly. If you omit the update mode it defaults to + /leaky where that makes sense (as before) or /readonly where required. + + The /noupdate option is now undocumented but still supported for + backwards compatibility. It is equivalent to /readonly except that in + ACLs where /readonly is required you may specify /leaky/noupdate or + /strict/noupdate which are treated the same as /readonly. + + A useful new feature is the /count= option. This is a generalization + of the per_byte option, so that you can measure the throughput of other + aggregate values. For example, the per_byte option is now equivalent + to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }. + + The per_rcpt option has been generalized using the /count= mechanism + (though it's more complicated than the per_byte equivalence). When it is + used in acl_smtp_rcpt, the per_rcpt option adds recipients to the + measured rate one at a time; if it is used later (e.g. in acl_smtp_data) + or in a non-SMTP ACL it adds all the recipients in one go. (The latter + /count=$recipients_count behaviour used to work only in non-SMTP ACLs.) + Note that using per_rcpt with a non-readonly update mode in more than + one ACL will cause the recipients to be double-counted. (The per_mail + and per_byte options don't have this problem.) + + The handling of very low rates has changed slightly. If the computed rate + is less than the event's count (usually one) then this event is the first + after a long gap. In this case the rate is set to the same as this event's + count, so that the first message of a spam run is counted properly. + + The major new feature is a mechanism for counting the rate of unique + events. The new per_addr option counts the number of different + recipients that someone has sent messages to in the last time period. It + behaves like per_rcpt if all the recipient addresses are different, but + duplicate recipient addresses do not increase the measured rate. Like + the /count= option this is a general mechanism, so the per_addr option + is equivalent to per_rcpt/unique=$local_part@$domain. You can, for + example, measure the rate that a client uses different sender addresses + with the options per_mail/unique=$sender_address. There are further + details in the main documentation. + +TF/05 Removed obsolete $Cambridge$ CVS revision strings. + +TF/06 Removed a few PCRE remnants. + +TF/07 Automatically extract Exim's version number from tags in the git + repository when doing development or release builds. + +PP/02 Raise smtp_cmd_buffer_size to 16kB. + Bugzilla 879.
