Assumptions at that stage could crash the receive process on malformed
input.
+JH/05 Bug 2215: Fix crash associated with dnsdb lookup done from DKIM ACL.
+ While running the DKIM ACL we operate on the Permanent memory pool so that
+ variables created with "set" persist to the DATA ACL. Also (at any time)
+ DNS lookups that fail create cache records using the Permanent pool. But
+ expansions release any allocations made on the current pool - so a dnsdb
+ lookup expansion done in the DKIM ACL releases the memory used for the
+ DNS negative-cache, and bad things result. Solution is to switch to the
+ Main pool for expansions.
+ While we're in that code, add checks on the DNS cache during store_reset,
+ active in the testsuite.
+ Problem spotted, and debugging aided, by Wolfgang Breyha.
+
+JH/06 Fix issue with continued-connections when the DNS shifts unreliably.
+ When none of the hosts presented to a transport match an already-open
+ connection, close it and proceed with the list. Previously we would
+ queue the message. Spotted by Lena with Yahoo, probably involving
+ round-robin DNS.
+
+JH/07 Bug 2214: Fix SMTP responses resulting from non-accept result of MIME ACL.
+ Previously a spurious "250 OK id=" response was appended to the proper
+ failure response.
+
+JH/08 The "support for" informational output now, which built with Content
+ Scanning support, has a line for the malware scanner interfaces compiled
+ in. Interface can be individually included or not at build time.
+
+JH/09 The "aveserver", "kavdaemon" and "mksd" interfaces are now not included
+ by the template makefile "src/EDITME". The "STREAM" support for an older
+ ClamAV interface method is removed.
+
+JH/10 Bug 2223: Fix mysql lookup returns for the no-data case (when the number of
+ rows affected is given instead).
