FormMail is Unix compatible. Any users who have versions of FormMail prior to v1.91, including the popular version 1.6, should upgrade immediately. v1.91 plugs several more spam-related security holes. The following fixes have also been implemented since v1.6: prevents unwanted access to environment variables and problem of receiving e-mail while using the redirect option. The script has two extra arrays (new in v1.7) you must define, but will not affect current forms or the way they appear after having been submitted.
