Re: What exactly is a token in a ruleset?

What exactly is a token and how is it delimited?

op.me:

   5.2.  D -- Define Macro

   [...]
           The  following  macros  are  defined  and/or used
      internally by sendmail for interpolation  into  argv's
      for  mailers or for other contexts.  The ones marked *
      are information passed  into  sendmail[16],
   [...]

      $o*  (Obsolete:  use  OperatorChars  option  instead.)
           The  set  of "operators" in addresses.  A list of
           characters which will be  considered  tokens  and
           which  will  separate  tokens when doing parsing.
           For example, if "@" were in the  $o  macro,  then
           the input "a@b" would be scanned as three tokens:
           "a," "@," and "b." Defaults to ".:@[]", which  is
           the  minimum set necessary to do RFC 822 parsing;
           a richer set of operators  is  ".:%@!/[]",  which
           adds  support  for  UUCP,  the  %-hack, and X.400
           addresses.
