Stop using a global, and JH/16 Fix ARC verification to do AS checks in reverse order. +JH/17 Support a "tls" option on the ${readsocket } expansion item. + +JH/18 Bug 2287: Fix the protocol name (eg utf8esmtp) for multiple messages + using the SMTPUTF8 option on their MAIL FROM commands, in one connection. + Previously the "utf8" would be re-prepended for every additional message. + +JH/19 Reject MAIL FROM commands with SMTPUTF8 when the facility was not advertised. + Previously thery were accepted, resulting in issues when attempting to + forward messages to a non-supporting MTA. + +PP/02 Let -n work with printing macros too, not just options. + +JH/20 Bug 2296: Fix cutthrough for >1 address redirection. Previously only + one parent address was copied, and bogus data was used at delivery-logging + time. Either a crash (after delivery) or bogus log data could result. + Discovery and analysis by Tim Stewart. + +PP/03 Make ${utf8clean:} expansion operator detect incomplete final character. + Previously if the string ended mid-character, we did not insert the + promised '?' replacement. + +PP/04 Documentation: current string operators work on bytes, not codepoints. + +JH/21 Change as many as possible of the global flags into one-bit bitfields; these + should pack well giving a smaller memory footprint so better caching and + therefore performance. Group the declarations where this can't be done so + that the byte-sized flag variables are not interspersed among pointer + variables, giving a better chance of good packing by the compiler. + +JH/22 Bug 1896: Fix the envelope from for DMARC forensic reports to be possibly + non-null, to avoid issues with sites running BATV. Previously reports were + sent with an empty envelope sender so looked like bounces. + +JH/23 Bug 2318: Fix the noerror command within filters. It wasn't working. + The ignore_error flag wasn't being returned from the filter subprocess so + was not set for later routers. Investigation and fix by Matthias Kurz. + +JH/24 Bug 2310: Raise a msg:fail:internal event for each undelivered recipient, + and a msg:complete for the whole, when a message is manually removed using + -Mrm. Developement by Matthias Kurz, hacked on by JH. + +JH/25 Avoid fixed-size buffers for pathnames in DB access. This required using + a "Gnu special" function, asprintf() in the DB utility binary builds; I + hope that is portable enough. + +JH/26 Bug 2311: Fix DANE-TA verification under GnuTLS. Previously it was also + requiring a known-CA anchor certificate; make it now rely entirely on the + TLSA as an anchor. Checking the name on the leaf cert against the name + on the A-record for the host is still done for TA (but not for EE mode). + +JH/27 Fix logging of proxy address. Previously, a pointless "PRX=[]:0" would be + included in delivery lines for non-proxied connections, when compiled with + SUPPORT_SOCKS and running with proxy logging enabled. + +JH/28 Bug 2314: Fire msg:fail:delivery event even when error is being ignored. + Developement by Matthias Kurz, tweaked by JH. While in that bit of code, + move the existing event to fire before the normal logging of message + failure so that custom logging is bracketed by normal logging. + +JH/29 Bug 2322: A "fail" command in a non-system filter (file) now fires the + msg:fail:internal event. Developement by Matthias Kurz. + +JH/30 Bug 2329: Increase buffer size used for dns lookup from 2k, which was + far too small for todays use of crypto signatures stored there. Go all + the way to the max DNS message size of 64kB, even though this might be + overmuch for IOT constrained device use. + +JH/31 Fix a bad use of a copy function, which could be used to pointlessly + copy a string over itself. The library routine is documented as not + supporting overlapping copies, and on MacOS it actually raised a SIGABRT. + +JH/32 For main options check_spool_space and check_inode_space, where the + platform supports 64b integers, support more than the previous 2^31 kB + (i.e. more than 2 TB). Accept E, P and T multipliers in addition to + the previous G, M, k. + +JH/33 Bug 2338: Fix the cyrus-sasl authenticator to fill in the + $authenticated_fail_id variable on authentication failure. Previously + it was unset. + +JH/34 Increase RSA keysize of autogen selfsign cert from 1024 to 2048. RHEL 8.0 + OpenSSL didn't want to use such a weak key. Do for GnuTLS also, and for + more-modern GnuTLS move from GNUTLS_SEC_PARAM_LOW to + GNUTLS_SEC_PARAM_MEDIUM. + +JH/35 OpenSSL: fail the handshake when SNI processing hits a problem, server + side. Previously we would continue as if no SNI had been received. + +JH/36 Harden the handling of string-lists. When a list consisted of a sole + "<" character, which should be a list-separator specification, we walked + off past the nul-terimation. + +JH/37 Bug 2341: Send "message delayed" warning MDNs (restricted to external + causes) even when the retry time is not yet met. Previously they were + not, meaning that when (say) an account was over-quota and temp-rejecting, + and multiple senders' messages were queued, only one sender would get + notified on each configured delay_warning cycle. + +JH/38 Bug 2351: Log failures to extract envelope addresses from message headers. + +JH/39 OpenSSL: clear the error stack after an SSL_accept(). With anon-auth + cipher-suites, an error can be left on the stack even for a succeeding + accept; this results in impossible error messages when a later operation + actually does fail. + Exim version 4.91 ----------------- @@ -442,7 +547,7 @@ JH/26 Fix DKIM bug: when the pseudoheader generated for signing was exactly line, the header hash was calculated to an incorrect value thanks to the (relaxed) space the fold became. -HS/02 Fix Bug 2130: large writes from the transport subprocess where chunked +HS/02 Fix Bug 2130: large writes from the transport subprocess were chunked and confused the parent.
