this always failed, probably leading to the usual downgrade to in-clear
connections.
+JH/21 Fix TLSA lookups. Previously dns_again_means_nonexist would affect
+ SERVFAIL results, which breaks the downgrade resistance of DANE. Change
+ to not checking that list for these lookups.
+
+JH/22 Bug 2434: Add connection-elapsed "D=" element to more connection
+ closure log lines.
+
+JH/23 Fix crash in string expansions. Previously, if an empty variable was
+ immediately followed by an expansion operator, a null-indirection read
+ was done, killing the process.
+
+JH/24 Bug 2997: When built with EXPERIMENTAL_DSN_INFO, bounce messages can
+ include an SMTP response string which is longer than that supported
+ by the delivering transport. Alleviate by wrapping such lines before
+ column 80.
+
+JH/25 Bug 2827: Restrict size of References: header in bounce messages to 998
+ chars (RFC limit). Previously a limit of 12 items was made, which with
+ a not-impossible References: in the message being bounced could still
+ be over-large and get stopped in the transport.
+
+JH/26 For a ${readsocket } in TLS mode, send a TLS Close Alert before the TCP
+ close. Previously a bare socket close was done.
+
+JH/27 Fix ${srs_encode ..}. Previously it would give a bad result for one day
+ every 1024 days.
+
+JH/28 Bug 2996: Fix a crash in the smtp transport. When finding that the
+ message being considered for delivery was already being handled by
+ another process, and having an SMTP connection already open, the function
+ to close it tried to use an uninitialized variable. This would afftect
+ high-volume sites more, especially when running mailing-list-style loads.
+ Pollution of logs was the major effect, as the other process delivered
+ the message. Found and partly investigated by Graeme Fowler.
