+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.

+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.
