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 and queue-list loops, for variables set + from spool message files. Do the same for the SMTP per-message loop, for + certain variables indirectly set in ACL operations. + +JH/29 Bug 2250: Fix a longstanding bug in heavily-pipelined SMTP input (such + as a multi-recipient message from a mailinglist manager). The coding had + an arbitrary cutoff number of characters while checking for more input; + enforced by writing a NUL into the buffer. This corrupted long / fast + input. The problem was exposed more widely when more pipelineing of SMTP + responses was introduced, and one Exim system was feeding another. + The symptom is log complaints of SMTP syntax error (NUL chars) on the + receiving system, and refused recipients seen by the sending system + (propating to people being dropped from mailing lists). + Discovered and pinpointed by David Carter. + +JH/30 The (EXPERIMENTAL_DMARC) variable $dmarc_ar_header is withdrawn, being + replaced by the ${authresults } expansion. + +JH/31 Bug 2257: Fix pipe transport to not use a socket-only syscall. + +HS/03 Set a handler for SIGTERM and call exit(3) if running as PID 1. This + allows proper process termination in container environments. + +JH/32 Bug 2258: Fix spool_wireformat in combination with LMTP transport. + Previously the "final dot" had a newline after it; ensure it is CR,LF. + +JH/33 SPF: remove support for the "spf" ACL condition outcome values "err_temp" + and "err_perm", deprecated since 4.83 when the RFC-defined words + "temperror" and "permerror" were introduced. + +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. + +JH/35 Cutthrough: for a final-dot response timeout (and nonunderstood responses) + in defer=pass mode supply a 450 to the initiator. Previously the message + would be spooled. + +PP/02 DANE: add dane_require_tls_ciphers SMTP Transport option; if unset, + tls_require_ciphers is used as before. + +HS/03 Malware Avast: Better match the Avast multiline protocol. Add + "pass_unscanned". Only tmpfails from the scanner are written to + the paniclog, as they may require admin intervention (permission + denied, license issues). Other scanner errors (like decompression + bombs) do not cause a paniclog entry. + +JH/36 Fix reinitialisation of DKIM logging variable between messages. + Previously it was possible to log spurious information in receive log + lines. + +JH/37 Bug 2255: Revert the disable of the OpenSSL session caching. This + triggered odd behaviour from Outlook Express clients. + +PP/03 Add util/renew-opendmarc-tlds.sh script for safe renewal of public + suffix list. Exim version 4.90
