FormMail
Formmail and its many variants, is a free open source web server CGI script that captures and processes form contents and then typically e-mails them to one or more recipients.
The script, originally created in Perl, was originally written in early 1993 by Reuven M. Lerner, as part of his work on The Tech, and was included in the archive of CGI programs made available by NCSA HTTPd. In its original form, it was called "form-mail.pl", and was released under the GNU General Public License.
The program was subsequently stripped of its copyright and authorship, renamed "FormMail", and publicized by Matt Wright as part of Matt's Script Archive.
