You have two options available to you:
1) If you are using and NT Server and have Administrative access, install BLAT or a similar sendmail substitute program on your system if possible.
2) Use "I-Web MailForm" or "SendMail.cgi" that is posted on cgi-resources.com under PERL:Form Processing. It uses the LWP module to open socket connections directly to the SMTP protocol and deliver mail the way sendmail does. Some other programs might be available for NT, but they may cost money.
