Previously, the arrivel of a notification or the latter being missed, and no further queue scheduled runs being initiated. This ouwld be more likely on high-load systems. -JH/12 Enforce a data synch check before emitting the 354 "go ahead". Previously - this was only done if a pre-data ACL was configured. - -JH/13 Refuse to accept a line "dot, LF" as end-of-DATA unless operating in +JH/12 Refuse to accept a line "dot, LF" as end-of-DATA unless operating in LF-only mode (as detected from the first header line). Previously we did accept that in (normal) CRLF mode; this has been raised as a possible attack scenario (under the name "smtp smuggling"). +JH/13 Add an fdatasync call for the received message data file in spool, before + loggging reception and sending the SMTP ack. Previously we only flushed + the stdio buffer so there was still the possibility of a disk error. + +JH/14 Bug 3061: Avoid a split log line when trying to rewrite a malformed + address. Previously, for the last address in a header line (commonly + there is only one) the terminating newline was part of the logged + information. + +JH/15 Bug 3061: Ensure a log line is written for a malformed address in a + header, when parsing for address-qualification. Previously one was only + written if there were rewrite rules. + +JH/16 Two-phase queue runs are now reported in the daemon startup log line and + in exiwhat output. + +JH/17 Bug 3064: Fix combination of "-q -R ". Introduction of + the multiple-queue-runners facility for 4.97 broke this, giving only a + one-time run of the queue. + +JH/18 Bug 3068: Log a warning for use of deprecated syntax in query-style + lookups. + +JH/19 Fix TLS startup. When the last expansion done before the initiation of a + TLS session resulted in a forced-fail, a misleading error was logged for + the expansino of tls_certificates. This would affect the common case of + that option being set (main-section options) but not having any variable + parts. It could also potentially affect tls_privatekeys. The underlyding + coding errors go back to 4.90 but were only exposed in 4.97. + +JH/20 Bug 3047: A recent (somewhere between 10.34 and 10.42) version of the + pcre2 library starting allocating 20kB rather than 112 bytes per match + call, which broke the 2GB total limitation on Exim's memory management + when a user had over 104207 messages stored and the appendfile + maildir_quota_directory_regex option is in use. Release the allocated + memory every thosand files to avoid this. + The same issue arises with the ACL regex condition, which is applied + to every line of a received message. + +JH/21 Bug 3059: Fix crash in smtp transport. When running for a message for + which all recipients had been handled (itself an issue) a null-pointer + deref was done on trying to write a retry record. Fix that by counting + the outstanding recipients before trying to transmit the message. + The situation arose for a second MX try within a transport run, when the + first had perm-rejected a recipient (the only one for the connection, in + the case seen) during pipelining, and then closed the TCP connection. + The transport classified that as an I/O error, leaving the message + outstanding but having marked up the recipient as dealt-with. It then + tried another MX because of the I/O error. Fix this by converting the + message-level status to ok if there was a close but all recipients were + dealt with. Thanks to Wolfgand Breyha for debug runs. + +JH/22 The ESMTP_LIMITS facility (RFC 9422) is promoted from experimental status + and is now controlled by the build-time option DISABLE_ESMTP_LIMITS. + +JH/23 Bug 3066: Avoid leaking lookup database credentials to log.
