Section 3 says:

   The exact rule is that any ASCII character, including control
   characters, may appear quoted, or in a quoted string.  When quoting
   is needed, the backslash character is used to quote the following
   character.  For example

      Abc\@def@example.com

   is a valid form of an email address.  Blank spaces may also appear,
   as in

      Fred\ Bloggs@example.com

   The backslash character may also be used to quote itself, e.g.,

      Joe.\\Blow@example.com
