  It is not just a matter of "safest".  The standards require quoting in
this case.

 You could have used an alias:

"Joe Richard.User": joeuser

  It looks up the alias EXACTLY.  Later, after all alias expansion is complete,
any "quotes" are removed.  Provided there is no \backquote the .forward is
then looked up (assuming the user exists).

  Presumably it would be possible.  There are an enormous number of
complications you have to think about.  The problem arises very rarely,
so it is questionable whether the effort is justified.  There are workarounds,
as my earlier posting mentioned, such as doing a final stage of aliasing in
the delivery agent after the unquoting has been done.
