Mail script in perl instead of using sendmail

[dzigner]

Hello
I have a perl script which uses sendmail to send a form to email. Since I have windows hosting, and dont have Sendmail program, I want to use alternate SMTP way to send it. Can some one help me? Here is the code:

# Location of the sendmail program
$sendmail = '/usr/bin/sendmail'; [COLOR=Sienna]---- this I have to change to what?[/COLOR]
# Your e-mail address here
$myemail = '[email protected]';

Please look at http://pixelbiz.des-us.com/userpages, where I have put up the script. I get this error on clicking on new page:
CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers.

Thanks
