+/* rfc822 says:
+        The local-part of an  addr-spec  in  a  mailbox  specification
+        (i.e.,  the  host's  name for the mailbox) is understood to be
+        whatever the receiving mail protocol server allows.  For exam-
+        ple,  some systems do not understand mailbox references of the
+        form "P. D. Q. Bach", but others do.
+
+        This specification treats periods (".") as lexical separators.
+        Hence,  their  presence  in  local-parts which are not quoted-
+        strings, is detected.   However,  such  occurrences  carry  NO
+        semantics.  That is, if a local-part has periods within it, an
+        address parser will divide the local-part into several tokens,
+        but  the  sequence  of  tokens will be treated as one uninter-
+        preted unit.  The sequence  will  be  re-assembled,  when  the
+        address is passed outside of the system such as to a mail pro-
+        tocol service.
