%MAILSERV-F-INDNOTAVA, Index for server is presently unavailable

      No file index information is currently available. This may
      or may not be a temporary condition. Try using the DIRECTORY
      command in the meantime.

  %MAILSERV-W-MAXPARM, too many parameters

      You supplied a parameter after the INDEX command. The INDEX
      command does not accept any parameters. Resend the command
      without any parameters.
