+Since version 4.91
+------------------
+
+JH/02 Bug 1007: Avoid doing logging from signal-handlers, as that can result in
+      non-signal-safe functions being used.
+
+JH/03 Bug 2269: When presented with a received message having a stupidly large
+      number of DKIM-Signature headers, disable DKIM verification to avoid
+      a resource-consumption attack.  The limit is set at twenty.
