Good point. Make it:

  # The second rule applies to all other domains, and is less strict. This
  ...

  deny    domains       = !+local_domains
          local_parts   = ^[./|] : ^.*[@%!] : ^.*/\\.\\./
          message       = restricted characters in address

=>

          local_parts   = ^[./|] : ^.*[@%!\'`#&?] : ^.*/\\.\\./
                                          ======

I'm not sure if the single-quote (') should necessarily be in the class though.
