+JH/04 Bug 2217: Tighten up the parsing of DKIM signature headers. Previously
+      we assumed that tags in the header were well-formed, and parsed the
+      element content after inspecting only the first char of the tag.
+      Assumptions at that stage could crash the receive process on malformed
+      input.
