+JH/24 Bug 3081: Fix a delivery process crash. When the router "errors_to"
+ option specified a fixed address, later rewriting on that address would
+ trip on the configuration data being readonly. Instead of modifying
+ in-place, copy data. Found and fixed by Peter Benie.
+
+JH/25 Bug 3079: Fix crash in dbmnz. When a key was present for zero-length
+ data a null pointer was followed. Find and testcase by Sebastian Bugge.
+
+JH/26 Fix encoding for an AUTH parameter on a MAIL FROM command. Previously
+ decimal 127 chars were not encoded, and lowercase hex was used for
+ encoded values. Outstanding since at least 1999.
+
+JH/27 Fix crash in logging. When a message with a large number of recipients
+ had been received, and logging of recipients is enabled, the buffer used
+ for logging could reach limit. A read using a null pointer would then
+ be done, resulting in a crash of the receiving process before an SMTP
+ ACK for the message was returned to the sending system. Duplicate
+ messages were created as a result.
+ Find and debug help by Mateusz Krawczyk

+JH/28 Bug 3086: Fix exinext for ipv6. Change the format of keys in the retry
+ DB, wrapping transport record bare-ip "host names" and ipv6
+ "host addresses" in square-brackets. This makes the parsing that
+ exinext does more reliable.
+
+JH/29 Bug 3087: Fix SRS encode. A zero-length quoted element in the local-part
+ would cause a crash.
+
+JH/30 Bug 3029: Avoid feeding Resent-From: to DMARC.
+
+JH/31 Bug 3027: For -bh / -bhc tests change to using the compressed form of
+ ipv6 addresses for the sender. Previously the uncompressed form was used,
+ and if used in textual form this would result in behavior difference
+ versus non-bh.
+
+JH/32 Bug 3096: MAIL before HELO/EHLO, where required by hosts_require_helo, is
+ now classed as a protocol error and subject to smtp_max_synprot_errors.
+
+JH/33 Bug 2994: A subdir dsearch lookup should permit a directory name that starts
+ ".." and has following characters.
