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. It can be left out + from a build by defining DISABLE_SOCKS. + + Exim version 4.86 ----------------- JH/01 Bug 1545: The smtp transport option "retry_include_ip_address" is now
