Yes, of course.  There is *support* for a limit, but the default
is to accept a large number of recipients per-message:

  confMAX_RCPTS_PER_MESSAGE  MaxRecipientsPerMessage

      [default: infinite] If set, allow no more than the specified
      number of recipients in an SMTP envelope.  Further recipients
      receive a 452 error code (i.e., they are deferred for the
      next delivery attempt).

You can set this easily, by modifying `sendmail.mc' to include:

  define(`confMAX_RCPTS_PER_MESSAGE', `20')
