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/16 GnuTLS: rework ciphersuite strings under recent library versions. Thanks + to changes apparently associated with TLS1.3 handling some of the APIs + previously used were either nonfunctional or inappropriate. Strings + like TLS1.3:ECDHE_SECP256R1__RSA_PSS_RSAE_SHA256__AES_256_GCM__AEAD:256 + and TLS1.2:ECDHE_SECP256R1__RSA_SHA256__AES_128_CBC__SHA256:128 replace + the previous TLS1.2:ECDHE_RSA_AES_256_GCM_SHA384:256 . + This affects log line X= elements, the $tls_{in,out}_cipher variables, + and the use of specific cipher names in the encrypted= ACL condition. + +JH/18 GnuTLS: fix $tls_out_ocsp under hosts_request_ocsp. Previously the + verification result was not updated unless hosts_require_ocsp applied. + +JH/19 Bug 2398: fix listing of a named-queue. Previously, even with the option + queue_list_requires_admin set to false, non-admin users were denied the + facility. + +JH/20 Bug 2389: fix server advertising of usable certificates, under GnuTLS in + directory-of-certs mode. Previously they were advertised despite the + documentation. + +JH/27 Bug 2404: Use the main-section configuration option "dsn_from" for + success-DSN messages. Previously the From: header was always the default + one for these; the option was ignored. + +PP/01 Unbreak heimdal_gssapi, broken in 4.92. + Exim version 4.92 -----------------
