Problem spotted, and debugging aided, by Wolfgang Breyha. +JH/06 Fix issue with continued-connections when the DNS shifts unreliably. + When none of the hosts presented to a transport match an already-open + connection, close it and proceed with the list. Previously we would + queue the message. Spotted by Lena with Yahoo, probably involving + round-robin DNS. + +JH/07 Bug 2214: Fix SMTP responses resulting from non-accept result of MIME ACL. + Previously a spurious "250 OK id=" response was appended to the proper + failure response. + +JH/08 The "support for" informational output now, which built with Content + Scanning support, has a line for the malware scanner interfaces compiled + in. Interface can be individually included or not at build time. + +JH/09 The "aveserver", "kavdaemon" and "mksd" interfaces are now not included + by the template makefile "src/EDITME". The "STREAM" support for an older + ClamAV interface method is removed. + +JH/10 Bug 2223: Fix mysql lookup returns for the no-data case (when the number of + rows affected is given instead). + +JH/11 The runtime Berkeley DB library version is now additionally output by + "exim -d -bV". Previously only the compile-time version was shown. + +JH/12 Bug 2230: Fix cutthrough routing for nonfirst messages in an initiating + SMTP connection. Previously, when one had more receipients than the + first, an abortive onward connection was made. Move to full support for + multiple onward connections in sequence, handling cutthrough connection + for all multi-message initiating connections. + +JH/13 Bug 2229: Fix cutthrough routing for nonstandard port numbers defined by + routers. Previously, a multi-recipient message would fail to match the + onward-connection opened for the first recipient, and cause its closure. + +JH/14 Bug 2174: A timeout on connect for a callout was also erroneously seen as + a timeout on read on a GnuTLS initiating connection, resulting in the + initiating connection being dropped. This mattered most when the callout + was marked defer_ok. Fix to keep the two timeout-detection methods + separate. + +JH/15 Relax results from ACL control request to enable cutthrough, in + unsupported situations, from error to silently (except under debug) + ignoring. This covers use with PRDR, frozen messages, queue-only and + fake-reject. + +HS/01 Fix Buffer overflow in base64d() (CVE-2018-6789) + +JH/16 Fix bug in DKIM verify: a buffer overflow could corrupt the malloc + metadata, resulting in a crash in free(). + +PP/01 Fix broken Heimdal GSSAPI authenticator integration. + Broken in f2ed27cf5, missing an equals sign for specified-initialisers. + Broken also in d185889f4, with init system revamp. + +JH/17 Bug 2113: Fix conversation closedown with the Avast malware scanner. + Previously we abruptly closed the connection after reading a malware- + found indication; now we go on to read the "scan ok" response line, + and send a quit. + +JH/18 Bug 2239: Enforce non-usability of control=utf8_downconvert in the mail + ACL. Previously, a crash would result. + +JH/19 Speed up macro lookups during configuration file read, by skipping non- + macro text after a replacement (previously it was only once per line) and + by skipping builtin macros when searching for an uppercase lead character. + +JH/20 DANE support moved from Experimental to mainline. The Makefile control + for the build is renamed. + +JH/21 Fix memory leak during multi-message connections using STARTTLS. A buffer + was allocated for every new TLS startup, meaning one per message. Fix + by only allocating once (OpenSSL) or freeing on TLS-close (GnuTLS). + +JH/22 Bug 2236: When a DKIM verification result is overridden by ACL, DMARC + reported the original. Fix to report (as far as possible) the ACL + result replacing the original. + +JH/23 Fix memory leak during multi-message connections using STARTTLS under + OpenSSL. Certificate information is loaded for every new TLS startup, + and the resources needed to be freed. + +JH/24 Bug 2242: Fix exim_dbmbuild to permit directoryless filenames. + +JH/25 Fix utf8_downconvert propagation through a redirect router. Previously it + was not propagated. + +JH/26 Bug 2253: For logging delivery lines under PRDR, append the overall + DATA response info to the (existing) per-recipient response info for + the "C=" log element. It can have useful tracking info from the + destination system. Patch from Simon Arlott. + +JH/27 Bug 2251: Fix ldap lookups that return a single attribute having zero- + length value. Previously this would segfault. + +HS/02 Support Avast multiline protoocol, this allows passing flags to + newer versions of the scanner. + +JH/28 Ensure that variables possibly set during message acceptance are marked + dead before release of memory in the daemon loop. This stops complaints + about them when the debug_store option is enabled. Discovered specifically + for sender_rate_period, but applies to a whole set of variables. + Do the same for the queue-runner loop, for variables set from spool + message files. + +PP/02 DANE: add dane_require_tls_ciphers SMTP Transport option; if unset, + tls_require_ciphers is used as before. + +JH/34 Re-introduce enforcement of no cutthrough delivery on transports having + transport-filters or DKIM-signing. The restriction was lost in the + consolidation of verify-callout and delivery SMTP handling. + Extend the restriction to also cover ARC-signing. + Exim version 4.90 -----------------
