+Exim version 4.95
+-----------------
+
+JH/01 Bug 1329: Fix format of Maildir-format filenames to match other mail-
+ related applications. Previously an "H" was used where available info
+ says that "M" should be, so change to match.
+
+JH/02 Bug 2587: Fix pam expansion condition. Tainted values are commonly used
+ as arguments, so an implementation trying to copy these into a local
+ buffer was taking a taint-enforcement trap. Fix by using dynamically
+ created buffers. Similar fix for radius expansion condition.
+
+JH/03 Bug 2586: Fix listcount expansion operator. Using tainted arguments is
+ reasonable, eg. to count headers. Fix by using dynamically created
+ buffers rather than a local. Do similar fixes for ACL actions "dcc",
+ "log_reject_target", "malware" and "spam"; the arguments are expanded
+ so could be handling tainted values.
+
+JH/04 Bug 2590: Fix -bi (newaliases). A previous code rearrangement had
+ broken the (no-op) support for this sendmail command. Restore it
+ to doing nothing, silently, and returning good status.
+
+JH/05 Bug 2593: Fix "vacation" in Exim filter. Previously, when a "once"
+ record path was given (or the default used) without a leading directory
+ path, an error occurred on trying to open it. Use the transport's working
+ directory.
+
+JH/06 Bug 2594: Change the name used for certificate name checks in the smtp
+ transport. Previously it was the name on the DNS A-record; use instead
+ the head of the CNAME chain leading there (if there is one). This seems
+ to align better with RFC 6125.
+
+JH/07 Bug 2597: Fix a resource leak. Using a lookup in obtaining a value for
+ smtp_accept_max_per_host allocated resources which were not released
+ when the limit was exceeded. This eventually crashed the daemon. Fix
+ by adding a relase action in that path.
+
+JH/08 Bug 2598: Fix verify ACL condition. The options for the condition are
+ expanded; previously using tainted values was rejected. Fix by using
+ dynamically-created buffers.
+
+JH/09 Relax restrictions on ACL verify condition needing access to message
+ headers. Previously they were only permitted in data and non-smtp ACLs;
+ permit also mime, dkim, prdr quit and notquit. Applies to header-syntax,
+ not_blind, header_sender and header_names_ascii verification.
+
+JH/10 Bug 2603: Fix coding of string copying to only evaluate arguments once.
+ Previously a macro used one argument twice; when called with the
+ argument as an expression having side-effects, incorrect operation
+ resulted. Use an inlineable function.
+
+JH/11 Bug 2604: Fix request to cutthrough-deliver when a connection is already
+ held open for a verify callout. Previously this wan not accounted for
+ and a corrupt onward SMTP conversation resulted.
+
+JH/12 Bug 2607: Fix the ${srs_encode } expansion to handle quoted local_parts.
+ Previously they were embedded naively in the constructed address; when
+ needed, strip the quoting and quote the entire local_part.
+ Also make the inbound_srs expansion condition handle quoting.
+
+JH/13 Fix dsearch "subdir" filter to ignore ".". Previously only ".." was
+ excluded, not matching the documentation.
+
+JH/14 Bug 2606: Fix a segfault in sqlite lookups. When no, or a bad, filename
+ was given for the sqlite_dbfile a trap resulted.
+
+JH/15 Bug 2620: Fix "spam" ACL condition. Previously, tainted values for the
+ "name" argument resulted in a trap. There is no reason to disallow such;
+ this was a coding error.
+
+JH/16 Bug 2615: Fix pause during message reception, on systems that have been
+ suspended/resumed. The Linux CLOCK_MONOTONIC does not account for time
+ spent suspended, ignoring the Posix definition. Previously we assumed
+ it did and a constant offset from real time could be used as a correction.
+ Change to using the same clock source for the start-of-message and the
+ post-message next-tick-wait. Also change to using CLOCK_BOOTTIME if it
+ exists, just to get a clock slightly more aligned to reality.
+
+JH/17 Bug 2295: Fix DKIM signing to always semicolon-terminate. Although the
+ RFC says it is optional some validators care. The missing char was not
+ intended but triggered by a line-wrap alignement. Discovery and fix by
+ Guillaume Outters, hacked on by JH.
+
+JH/18 Bug 2617: Fix a taint trap in parse_fix_phrase(). Previously when the
+ name being quoted was tainted a trap would be taken. Fix by using
+ dynamicaly created buffers. The routine could have been called by a
+ rewrite with the "h" flag, by using the "-F" command-line option, or
+ by using a "name=" option on a control=submission ACL modifier.
+
+JH/19 SPF: change the Authentication-Results expansion component to give
+ smtp.helo when the sender domain is empty. Previously it gave
+ "smtp.mailfrom=<>"
+
+JH/20 Bug 2631: ACL dnslist conditions now ignore and log any lookups returns
+ not in 127.0.0.0/8 to help in spotting list domains taken over by a
+ domain-parking registrar.
+
+JH/21 Bug 2630: Fix eol-replacement string for the ${readsocket } expansion.
+ Previously when a whitespace character was specified it was not inserted
+ after removing the newline.
+
+JH/22 Bug 2265: Force SNI usage for smtp transport DANE'd connections, to be
+ the domain part of the recipient address. This overrides any tls_sni
+ option set, which was previously used.
+
+JH/23 Logging: with the +tls_sni log_selector, do not wrap the received SNI
+ in quotes.
+
+JH/24 Bug 2634: Fix a taint trap seen on NetBSD: the testing coded for
+ is_tainted() had an off-by-one error in the overenthusiastic direction.
+ Find and fix by Gavan. Although NetBSD is not a supported platform for
+ 4.94 this bug could affect other platforms.
+
+PP/01 Fix default prime selection to be consistent.
+ One path used ike23 still, instead of exim.dev.20160529.3; now both
+ execution flows will use the same DH primes (currently
+ exim.dev.20160529.3).
+
+JH/25 OpenSSL: Fix back-compatibiility behaviour surrounding tls_certificates
+ option in smtp transport, to match the documentation. Previously
+ verification was not being done in some cases where it should have been.
+
+
+Exim version 4.94
+-----------------
+
+JH/01 Avoid costly startup code when not strictly needed. This reduces time
+ for some exim process initialisations. It does mean that the logging
+ of TLS configuration problems is only done for the daemon startup.
+
+JH/02 Early-pipelining support code is now included unless disabled in Makefile.
+
+JH/03 DKIM verification defaults no long accept sha1 hashes, to conform to
+ RFC 8301. They can still be enabled, using the dkim_verify_hashes main
+ option.
+
+JH/04 Support CHUNKING from an smtp transport using a transport_filter, when
+ DKIM signing is being done. Previously a transport_filter would always
+ disable CHUNKING, falling back to traditional DATA.
+
+JH/05 Regard command-line recipients as tainted.
+
+JH/06 Bug 340: Remove the daemon pid file on exit, when due to SIGTERM.
+
+JH/07 Bug 2489: Fix crash in the "pam" expansion condition. It seems that the
+ PAM library frees one of the arguments given to it, despite the
+ documentation. Therefore a plain malloc must be used.
+
+JH/08 Bug 2491: Use tainted buffers for the transport smtp context. Previously
+ on-stack buffers were used, resulting in a taint trap when DSN information
+ copied from a received message was written into the buffer.
+
+JH/09 Bug 2493: Harden ARC verify against Outlook, whick has been seen to mix
+ the ordering of its ARC headers. This caused a crash.
+
+JH/10 Bug 2492: Use tainted memory for retry record when needed. Previously when
+ a new record was being constructed with information from the peer, a trap
+ was taken.
+
+JH/11 Bug 2494: Unset the default for dmarc_tld_file. Previously a naiive
+ installation would get error messages from DMARC verify, when it hit the
+ nonexistent file indicated by the default. Distros wanting DMARC enabled
+ should both provide the file and set the option.
+ Also enforce no DMARC verification for command-line sourced messages.
+
+JH/12 Fix an uninitialised flag in early-pipelining. Previously connections
+ could, depending on the platform, hang at the STARTTLS response.
+
+JH/13 Bug 2498: Reset a counter used for ARC verify before handling another
+ message on a connection. Previously if one message had ARC headers and
+ the following one did not, a crash could result when adding an
+ Authentication-Results: header.
+
+JH/14 Bug 2500: Rewind some of the common-coding in string handling between the
+ Exim main code and Exim-related utities. The introduction of taint
+ tracking also did many adjustments to string handling. Since then, eximon
+ frequently terminated with an assert failure.
+
+JH/15 When PIPELINING, synch after every hundred or so RCPT commands sent and
+ check for 452 responses. This slightly helps the inefficieny of doing
+ a large alias-expansion into a recipient-limited target. The max_rcpt
+ transport option still applies (and at the current default, will override
+ the new feature). The check is done for either cause of synch, and forces
+ a fast-retry of all 452'd recipients using a new MAIL FROM on the same
+ connection. The new facility is not tunable at this time.
+
+JH/16 Fix the variables set by the gsasl authenticator. Previously a pointer to
+ library live data was being used, so the results became garbage. Make
+ copies while it is still usable.
+
+JH/17 Logging: when the deliver_time selector ise set, include the DT= field
+ on delivery deferred (==) and failed (**) lines (if a delivery was
+ attemtped). Previously it was only on completion (=>) lines.
+
+JH/18 Authentication: the gsasl driver not provides the $authN variables in time
+ for the expansion of the server_scram_iter and server_scram_salt options.
+
+WB/01 SPF: DNS lookups for the obsolete SPF RR type done by the libspf2 library
+ are now specifically given a NO_DATA response without hitting the system
+ resolver. The library goes on to do the now-standard TXT lookup.
+ Use of dnsdb lookups is not affected.
+
+JH/19 Bug 2507: Modules: on handling a dynamic-module (lookups) open failure,
+ only retrieve the errormessage once. Previously two calls to dlerror()
+ were used, and the second one (for mainlog/paniclog) retrieved null
+ information.
+
+JH/20 Taint checking: disallow use of tainted data for
+ - the appendfile transport file and directory options
+ - the pipe transport command
+ - the autoreply transport file, log and once options
+ - file names used by the redirect router (including filter files)
+ - named-queue names
+ - paths used by single-key lookups
+ Previously this was permitted.
+
+JH/21 Bug 2501: Fix init call in the heimdal authenticator. Previously it
+ adjusted the size of a major service buffer; this failed because the
+ buffer was in use at the time. Change to a compile-time increase in the
+ buffer size, when this authenticator is compiled into exim.
+
+JH/22 Taint-checking: move to safe-mode taint checking on all platforms. The
+ previous fast-mode was untenable in the face of glibs using mmap to
+ support larger malloc requests.
+
+PP/01 Update the openssl_options possible values through OpenSSL 1.1.1c.
+ New values supported, if defined on system where compiled:
+ allow_no_dhe_kex, cryptopro_tlsext_bug, enable_middlebox_compat,
+ no_anti_replay, no_encrypt_then_mac, prioritize_chacha, tlsext_padding
+
+JH/23 Performance improvement in the initial phase of a two-pass queue run. By
+ running a limited number of proceses in parallel, a benefit is gained. The
+ amount varies with the platform hardware and load. The use of the option
+ queue_run_in_order means we cannot do this, as ordering becomes
+ indeterminate.
+
+JH/24 Bug 2524: fix the cyrus_sasl auth driver gssapi usage. A previous fix
+ had introduced a string-copy (for ensuring NUL-termination) which was not
+ appropriate for that case, which can include embedded NUL bytes in the
+ block of data. Investigation showed the copy to actually be needless, the
+ data being length-specified.
+
+JH/25 Fix use of concurrent TLS connections under GnuTLS. When a callout was
+ done during a receiving connection, and both used TLS, global info was
+ used rather than per-connection info for tracking the state of data
+ queued for transmission. This could result in a connection hang.
+
+JH/26 Fix use of the SIZE parameter on MAIL commands, on continued connections.
+ Previously, when delivering serveral messages down a single connection
+ only the first would provide a SIZE. This was due to the size information
+ not being properly tracked.
+
+JH/27 Bug 2530: When operating in a timezone with sub-minute offset, such as
+ TAI (at 37 seconds currently), pretend to be in UTC for time-related
+ expansion and logging. Previously, spurious values such as a future
+ minute could be seen.
+
+JH/28 Bug 2533: Fix expansion of ${tr } item. When called in some situations
+ it could crash from a null-deref. This could also affect the
+ ${addresses: } operator and ${readsock } item.
+
+JH/29 Bug 2537: Fix $mime_part_count. When a single connection had a non-mime
+ message following a mime one, the variable was not reset.
+
+JH/30 When an pipelined-connect fails at the first response, assume incorrect
+ cached capability (perhaps the peer reneged?) and immediately retry in
+ non-pipelined mode.
+
+JH/31 Fix spurious detection of timeout while writing to transport filter.
+
+JH/32 Bug 2541: Fix segfault on bad cmdline -f (sender) argument. Previously
+ an attempt to copy the string was made before checking it.
+
+JH/33 Fix the dsearch lookup to return an untainted result. Previously the
+ taint of the lookup key was maintained; we now regard the presence in the
+ filesystem as sufficient validation.
+
+JH/34 Fix the readsocket expansion to not segfault when an empty "options"
+ argument is supplied.
+
+JH/35 The dsearch lookup now requires that the directory is an absolute path.
+ Previously this was not checked, and nonempty relative paths made an
+ access under Exim's current working directory.
+
+JH/36 Bug 2554: Fix msg:defer event for the hosts_max_try_hardlimit case.
+ Previously no event was raised.
+
+JH/37 Bug 2552: Fix the check on spool space during reception to use the SIZE
+ parameter supplied by the sender MAIL FROM command. Previously it was
+ ignored, and only the check_spool_space option value for the required
+ leeway checked.
+
+JH/38 Fix $dkim_key_length. This should, after a DKIM verification, present
+ the size of the signing public-key. Previously it was instead giving
+ the size of the signature hash.
+
+JH/39 DKIM verification: the RFC 8301 restriction on sizes of RSA keys is now
+ the default. See the (new) dkim_verify_min_keysizes option.
+
+JH/40 Fix a memory-handling bug: when a connection carried multiple messages
+ and an ACL use a lookup for checking either the local_part or domain,
+ stale data could be accessed. Ensure that variable references are
+ dropped between messages.
+
+JH/41 Bug 2571: Fix SPA authenticator. Running as a server, an offset supplied
+ by the client was not checked as pointing within response data before
+ being used. A malicious client could thus cause an out-of-bounds read and
+ possibly gain authentication. Fix by adding the check.
+
+JH/42 Internationalisation: change the default for downconversion in the smtp
+ transport to be "if needed". Previously it was "as previously set" for
+ the message, which usually meant "if needed" for message-submission but
+ "no" for everything else. However, MTAs have been seen using SMTPUTF8
+ even when the envelope addresses did not need it, resulting in forwarding
+ failures to non-supporting MTAs. A downconvert in such cases will be
+ a no-op on the addresses, merely dropping the use of SMTPUTF8 by the
+ transport. The change does mean that addresses needing conversion will
+ be converted when previously a delivery failure would occur.
+
+JH/43 Fix possible long line in DSN. Previously when a very long SMTP error
+ response was received it would be used unchecked in a fail-DSN, violating
+ standards on line-length limits. Truncate if needed.
+
+HS/01 Remove parameters of the link to www.open-spf.org. The linked form
+ doesn't work. (Additionally add a new main config option to configure the
+ spf_smtp_comment)
+
+
+Exim version 4.93
+-----------------
+
+JH/01 OpenSSL: With debug enabled output keying information sufficient, server
+ side, to decode a TLS 1.3 packet capture.
+
+JH/02 OpenSSL: Suppress the sending of (stateful) TLS1.3 session tickets.
+ Previously the default library behaviour applied, sending two, each in
+ its own TCP segment.
+
+JH/03 Debug output for ACL now gives the config file name and line number for
+ each verb.
+
+JH/04 The default received_header_text now uses the RFC 8314 tls cipher clause.
+
+JH/05 DKIM: ensure that dkim_domain elements are lowercased before use.
+
+JH/06 Fix buggy handling of autoreply bounce_return_size_limit, and a possible
+ buffer overrun for (non-chunking) other transports.
+
+JH/07 GnuTLS: Our use of late (post-handshake) certificate verification, under
+ TLS1.3, means that a server rejecting a client certificate is not visible
+ to the client until the first read of encrypted data (typically the
+ response to EHLO). Add detection for that case and treat it as a failed
+ TLS connection attempt, so that the normal retry-in-clear can work (if
+ suitably configured).
+
+JB/01 Bug 2375: fix expansions of 822 addresses having comments in local-part
+ and/or domain. Found and fixed by Jason Betts.
+
+JH/08 Add hardening against SRV & TLSA lookups the hit CNAMEs (a nonvalid
+ configuration). If a CNAME target was not a wellformed name pattern, a
+ crash could result.
+
+JH/09 Logging: Fix initial listening-on line for multiple ports for an IP when
+ the OS reports them interleaved with other addresses.
+
+JH/10 OpenSSL: Fix aggregation of messages. Previously, when PIPELINING was
+ used both for input and for a verify callout, both encrypted, SMTP
+ responses being sent by the server could be lost. This resulted in
+ dropped connections and sometimes bounces generated by a peer sending
+ to this system.
+
+JH/11 Harden plaintext authenticator against a badly misconfigured client-send
+ string. Previously it was possible to cause undefined behaviour in a
+ library routine (usually a crash). Found by "zerons".
+
+JH/12 Bug 2384: fix "-bP smtp_receive_timeout". Previously it returned no
+ output.
+
+JH/13 Bug 2386: Fix builds with Dane under LibreSSL 2.9.0 onward. Some old
+ API was removed, so update to use the newer ones.
+
+JH/14 Bug 1891: Close the log file if receiving a non-smtp message, without
+ any timeout set, is taking a long time. Previously we would hang on to a
+ rotated logfile "forever" if the input was arriving with long gaps
+ (a previous attempt to fix addressed lack, for a long time, of initial
+ input).
+
+HS/01 Bug 2390: Use message_id for tempfile creation to avoid races in a
+ shared (NFS) environment. The length of the tempfile name is now
+ 4 + 16 ("hdr.$message_exim_id") which might break on file
+ systems which restrict the file name length to lower values.
+ (It was "hdr.$pid".)
+
+HS/02 Bug 2390: Use message_id for tempfile creation to avoid races in a
+ shared (NFS) environment.
+
+HS/03 Bug 2392: exigrep does case sensitive *option* processing (as it
+ did for all versions <4.90). Notably -M, -m, --invert, -I may be
+ affected.
+
+JH/15 Use unsigned when creating bitmasks in macros, to avoid build errors
+ on some platforms for bit 31.
+
+JH/16 GnuTLS: rework ciphersuite strings under recent library versions. Thanks
+ to changes apparently associated with TLS1.3 handling some of the APIs
+ previously used were either nonfunctional or inappropriate. Strings
+ like TLS1.3:ECDHE_SECP256R1__RSA_PSS_RSAE_SHA256__AES_256_GCM__AEAD:256
+ and TLS1.2:ECDHE_SECP256R1__RSA_SHA256__AES_128_CBC__SHA256:128 replace
+ the previous TLS1.2:ECDHE_RSA_AES_256_GCM_SHA384:256 .
+ This affects log line X= elements, the $tls_{in,out}_cipher variables,
+ and the use of specific cipher names in the encrypted= ACL condition.
+
+JH/17 OpenSSL: the default openssl_options now disables ssl_v3.
+
+JH/18 GnuTLS: fix $tls_out_ocsp under hosts_request_ocsp. Previously the
+ verification result was not updated unless hosts_require_ocsp applied.
+
+JH/19 Bug 2398: fix listing of a named-queue. Previously, even with the option
+ queue_list_requires_admin set to false, non-admin users were denied the
+ facility.
+
+JH/20 Bug 2389: fix server advertising of usable certificates, under GnuTLS in
+ directory-of-certs mode. Previously they were advertised despite the
+ documentation.
+
+JH/21 The smtp transport option "hosts_noproxy_tls" is now unset by default.
+ A single TCP connection by a client will now hold a TLS connection open
+ for multiple message deliveries, by default. Previously the default was to
+ not do so.
+
+JH/22 The smtp transport option "hosts_try_dane" now enables all hosts by
+ default. If built with the facility, DANE will be used. The facility
+ SUPPORT_DANE is now enabled in the prototype build Makefile "EDITME".
+
+JH/23 The build default is now for TLS to be included; the SUPPORT_TLS define
+ is replaced with DISABLE_TLS. Either USE_GNUTLS or (the new) USE_OPENSSL
+ must be defined and you must still, unless you define DISABLE_TLS, manage
+ the the include-dir and library-file requirements that go with that
+ choice. Non-TLS builds are still supported.
+
+JH/24 Fix duplicated logging of peer name/address, on a transport connection-
+ reject under TFO.
+
+JH/25 The smtp transport option "hosts_try_fastopen" now enables all hosts by
+ default. If the platform supports and has the facility enabled, it will
+ be requested on all coneections.
+
+JH/26 The PIPE_CONNECT facility is promoted from experimental status and is now
+ controlled by the build-time option SUPPORT_PIPE_CONNECT.
+
+PP/01 Unbreak heimdal_gssapi, broken in 4.92.
+
+JH/27 Bug 2404: Use the main-section configuration option "dsn_from" for
+ success-DSN messages. Previously the From: header was always the default
+ one for these; the option was ignored.
+
+JH/28 Fix the timeout on smtp response to apply to the whole response.
+ Previously it was reset for every read, so a teergrubing peer sending
+ single bytes within the time limit could extend the connection for a
+ long time. Credit to Qualsys Security Advisory Team for the discovery.
+
+JH/29 Fix DSN Final-Recipient: field. Previously it was the post-routing
+ delivery address, which leaked information of the results of local
+ forwarding. Change to the original envelope recipient address, per
+ standards.
+
+JH/30 Bug 2411: Fix DSN generation when RFC 3461 failure notification is
+ requested. Previously not bounce was generated and a log entry of
+ error ignored was made.
+
+JH/31 Avoid re-expansion in ${sort } expansion. (CVE-2019-13917)
+
+JH/32 Introduce a general tainting mechanism for values read from the input
+ channel, and values derived from them. Refuse to expand any tainted
+ values, to catch one form of exploit.
+
+JH/33 Bug 2413: Fix dkim_strict option. Previously the expansion result
+ was unused and the unexpanded text used for the test. Found and
+ fixed by Ruben Jenster.
+
+JH/34 Fix crash after TLS shutdown. When the TCP/SMTP channel was left open,
+ an attempt to use a TLS library read routine dereffed a nul pointer,
+ causing a segfault.
+
+JH/35 Bug 2409: filter out-of-spec chars from callout response before using
+ them in our smtp response.
+
+JH/36 Have the general router option retry_use_local_part default to true when
+ any of the restrictive preconditions are set (to anything). Previously it
+ was only for check_local user. The change removes one item of manual
+ configuration which is required for proper retries when a remote router
+ handles a subset of addresses for a domain.
+
+JH/37 Appendfile: when evaluating quota use (non-quota_size_regex) take the file
+ link count into consideration.
+
+HS/04 Fix handling of very log lines in -H files. If a -<key> <value> line
+ caused the extension of big_buffer, the following lines were ignored.
+
+JH/38 Bug 1395: Teach the DNS negative-cache about TTL value from the SOA in
+ accordance with RFC 2308. Previously there was no expiry, so a longlived
+ receive process (eg. due to ACL delays) versus a short SOA value could
+ surprise.
+
+HS/05 Handle trailing backslash gracefully. (CVE-2019-15846)
+
+JH/39 Promote DMARC support to mainline.
+
+JH/40 Bug 2452: Add a References: header to DSNs.
+
+JH/41 With GnuTLS 3.6.0 (and later) do not attempt to manage Diffie-Hellman
+ parameters. The relevant library call is documented as "Deprecated: This
+ function is unnecessary and discouraged on GnuTLS 3.6.0 or later. Since
+ 3.6.0, DH parameters are negotiated following RFC7919."
+
+HS/06 Change the default of dnssec_request_domains to "*"
+
+JH/42 Bug 2545: Fix CHUNKING for all RCPT commands rejected. Previously we
+ carried on and emitted a BDAT command, even when PIPELINING was not
+ active.
+
+JH/43 Bug 2465: Fix taint-handling in dsearch lookup. Previously a nontainted
+ buffer was used for the filename, resulting in a trap when tainted
+ arguments (eg. $domain) were used.
+
+JH/44 With OpenSSL 1.1.1 (onwards) disable renegotiation for TLS1.2 and below;
+ recommended to avoid a possible server-load attack. The feature can be
+ re-enabled via the openssl_options main cofiguration option.
+
+JH/45 local_scan API: documented the current smtp_printf() call. This changed
+ for version 4.90 - adding a "more data" boolean to the arguments.
+ Bumped the ABI version number also, this having been missed previously;
+ release versions 4.90 to 4.92.3 inclusive were effectively broken in
+ respect of usage of smtp_printf() by either local_scan code or libraries
+ accessed via the ${dlfunc } expansion item. Both will need coding
+ adjustment for any calls to smtp_printf() to match the new function
+ signature; a FALSE value for the new argument is always safe.
+
+JH/46 FreeBSD: fix use of the sendfile() syscall. The shim was not updating
+ the file-offset (which the Linux syscall does, and exim expects); this
+ resulted in an indefinite loop.
+
+JH/47 ARC: fix crash in signing, triggered when a configuration error failed
+ to do ARC verification. The Authentication-Results: header line added
+ by the configuration then had no ARC item.
