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. Previous 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). + Exim version 4.92 -----------------
