JH/06 Bug 340: Remove the daemon pid file on exit, whe 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) + Previously this was permitted. + Exim version 4.93 -----------------
