       dnssec_require_domains, dnssec_request_domains, srv_fail_domains,
       mx_fail_domains.
 
+JH/45 Use a (new) separate store pool-pair for DKIM verify working data.
+      Previously the permanent pool was used, so the sore could not be freed.
+      This meant a connection with many messages would use continually-growing
+      memory.
+
+JH/46 Use an exponentially-increasing block size when malloc'ing store.  Do it
+      per-pool so as not to waste too much space.  Previously a constant size
+      was used which resulted in O(n^2) behaviour; now we get O(n log n) making
+      DOS attacks harder.  The cost is wasted memory use in the larger blocks.
+
+JH/47 Use explicit alloc/free for DNS lookup workspace.  This permits using the
+      same space repeatedly, and a smaller process footprint.
