* Wed Jun 29 2022 Stefan Schubert - Moved logrotate files from user specific directory /etc/logrotate.d to vendor specific directory /usr/etc/logrotate.d.
* Mon Jun 27 2022 Peter Wullinger - update to exim 4.96
* Move from using the pcre library to pcre2.
* Constification work in the filters module required a major version bump for the local-scan API. Specifically, the \"headers_charset\" global which is visible via the API is now const and may therefore not be modified by local-scan code.
* Bug 2819: speed up command-line messages being read in. Previously a time check was being done for every character; replace that with one per buffer.
* Bug 2815: Fix ALPN sent by server under OpenSSL. Previously the string sent was prefixed with a length byte.
* Change the SMTP feature name for pipelining connect to be compliant with RFC 5321. Previously Dovecot (at least) would log errors during submission.
* Fix macro-definition during \"-be\" expansion testing. The move to write-protected store for macros had not accounted for these runtime additions; fix by removing this protection for \"-be\" mode.
* Convert all uses of select() to poll().
* Fix use of $sender_host_name in daemon process. When used in certain main-section options or in a connect ACL, the value from the first ever connection was never replaced for subsequent connections.
* Bug 2838: Fix for i32lp64 hard-align platforms
* Bug 2845: Fix handling of tls_require_ciphers for OpenSSL when a value with underbars is given.
* Bug 1895: TLS: Deprecate RFC 5114 Diffie-Hellman parameters.
* Debugging initiated by an ACL control now continues through into routing and transport processes.
* The \"expand\" debug selector now gives more detail, specifically on the result of expansion operators and items.
* Bug 2751: Fix include_directory in redirect routers. Previously a bad comparison between the option value and the name of the file to be included was done, and a mismatch was wrongly identified.
* Support for Berkeley DB versions 1 and 2 is withdrawn.
* When built with NDBM for hints DB\'s check for nonexistence of a name supplied as the db file-pair basename.
* Remove the \"allow_insecure_tainted_data\" main config option and the \"taint\" log_selector.
* Fix static address-list lookups to properly return the matched item. Previously only the domain part was returned.
* The ${run} expansion item now expands its command string elements after splitting. Previously it was before; the new ordering makes handling zero-length arguments simpler.
* Taint-check exec arguments for transport-initiated external processes. Previously, tainted values could be used. This affects \"pipe\", \"lmtp\" and \"queryprogram\" transport, transport-filter, and ETRN commands. The ${run} expansion is also affected: in \"preexpand\" mode no part of the command line may be tainted, in default mode the executable name may not be tainted.
* Fix CHUNKING on a continued-transport. Previously the usabilility of the facility was not passed across execs, and only the first message passed over a connection could use BDAT; any further ones using DATA.
* Support the PIPECONNECT facility in the smtp transport when the helo_data uses $sending_ip_address and an interface is specified.
* OpenSSL: fix transport-required OCSP stapling verification under session resumption.
* TLS resumption: the key for session lookup in the client now includes more info that a server could potentially use in configuring a TLS session, avoiding oferring mismatching sessions to such a server.
* Fix string_copyn() for limit greater than actual string length.
* Bug 2886: GnuTLS: Do not free the cached creds on transport connection close; it may be needed for a subsequent connection.
* Fix CHUNKING for a second message on a connection when the first was rejected.
* Fix ${srs_encode ...} to handle an empty sender address, now returning an empty address.
* Bug 2855: Handle a v4mapped sender address given us by a frontending proxy.
* Wed Jan 19 2022 Peter Wullinger - disable ProtectHome=, it prevents local delivery (bsc#1194810)
* Wed Sep 29 2021 Peter Wullinger - update to exim 4.95
* includes taintwarn (taintwarn.patch)

* LMDB lookups with single key
* smtp transport option \"message_linelength_limit\"
* optionally ignore lookup caches
* quota checking for appendfile transport during message reception
* sqlite lookups allow a \"file=\" option
* lsearch lookups allow a \"ret=full\" option
* command line option for the notifier socket

* CVE-2020-28025: Heap out-of-bounds read in pdkim_finish_bodyhash()
* Wed Apr 28 2021 wullingerAATTrz.uni-kiel.de- update to exim-4.94.1
* Fix security issue in BDAT state confusion. Ensure we reset known-good where we know we need to not be reading BDAT data, as a general case fix, and move the places where we switch to BDAT mode until after various protocol state checks. Fixes CVE-2020-BDATA reported by Qualys.
* Fix security issue in SMTP verb option parsing (CVE-2020-EXOPT)
* Fix security issue with too many recipients on a message (to remove a known security problem if someone does set recipients_max to unlimited, or if local additions add to the recipient list). Fixes CVE-2020-RCPTL reported by Qualys.
* Fix CVE-2020-28016 (PFPZA): Heap out-of-bounds write in parse_fix_phrase()
* Fix security issue CVE-2020-PFPSN and guard against cmdline invoker providing a particularly obnoxious sender full name.

* Mon Aug 24 2020 wullingerAATTrz.uni-kiel.de- bring back missing exim_db.8 manual page (fixes bsc#1173693)
* Mon Jun 08 2020 wullingerAATTrz.uni-kiel.de- bring in changes from current +fixes (lots of taint check fixes)
* 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.
* 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.
* 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.
* 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.
* Tue Jun 02 2020 wullingerAATTrz.uni-kiel.de- update to exim 4.94
* some transports now refuse to use tainted data in constructing their delivery location this WILL BREAK configurations which are not updated accordingly. In particular: any Transport use of $local_user which has been relying upon check_local_user far away in the Router to make it safe, should be updated to replace $local_user with $local_part_data.
* Attempting to remove, in router or transport, a header name that ends with an asterisk (which is a standards-legal name) will now result in all headers named starting with the string before the asterisk being removed.
* Tue May 19 2020 wullingerAATTrz.uni-kiel.de- switch pretrans to use lua (fixes bsc#1171877)
* Tue May 12 2020 wullingerAATTrz.uni-kiel.de- bring changes from current in +fixes branch (patch-exim-fixes-ee83de04d3087efaf808d1f2235a988275c2ee94)
* fixes CVE-2020-12783 (bsc#1171490)
* Regard command-line recipients as tainted.
* Bug 2489: Fix crash in the \"pam\" expansion condition.
* Use tainted buffers for the transport smtp context.
* Bug 2493: Harden ARC verify against Outlook, which has been seen to mix the ordering of its ARC headers. This caused a crash.
* 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.
* Bug 2494: Unset the default for dmarc_tld_file.
* Fix an uninitialised flag in early-pipelining. Previously connections could, depending on the platform, hang at the STARTTLS response.
* 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.
* Bug 2500: Rewind some of the common-coding in string handling between the Exim main code and Exim-related utities.
* Fix the variables set by the gsasl authenticator.
* Bug 2507: Modules: on handling a dynamic-module (lookups) open failure, only retrieve the errormessage once.
* 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.
* Wed Apr 01 2020 wullingerAATTrz.uni-kiel.de- don\'t create logfiles during install
* fixes CVE-2020-8015 (bsc#1154183)
* Mon Jan 13 2020 wullingerAATTrz.uni-kiel.de- add a spec-file workaround for bsc#1160726
* Tue Jan 07 2020 wullingerAATTrz.uni-kiel.de- update to exim 4.93.0.4 (+fixes release)
* 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.
* Early-pipelining support code is now included unless disabled in Makefile.
* 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.
* 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.
* Regard command-line receipients as tainted.
* Bug 340: Remove the daemon pid file on exit, whe due to SIGTERM.
* 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.
* 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.
* Bug 2493: Harden ARC verify against Outlook, whick has been seen to mix the ordering of its ARC headers. This caused a crash.
* 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.
* 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.
* Fix an uninitialised flag in early-pipelining. Previously connections could, depending on the platform, hang at the STARTTLS response.
* 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.
* 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.
* 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.
* 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.
* 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.
* Authentication: the gsasl driver not provides the $authN variables in time for the expansion of the server_scram_iter and server_scram_salt options.
* Thu Jan 02 2020 wullingerAATTrz.uni-kiel.despec file cleanup to make update work- add docdir to spec
