Trying to send mail on win2003 server

Hi, sorry if this is in the wrong forum. I have been trying for a while now but can't figure out how to get my script to send email via win2003 server. This code was given to me and works well on Linux, but my hosting provider uses windows platform. I'm trying to figure out what I need to do to make it work. Perl is installed on the server which is what my main program is built in. Below is a snippit from my .pl file that handles the email function. Is there a specific place I need to tell it where/name my smtp server? If so where is this done. If anyone needs to see the entire file I will gladly provide it. A huge thanks to anyone who can help shed some light on this.

open (MAIL, "|/usr/sbin/sendmail -t") || warn print "Can't send mail: $!\n";

print MAIL<<"EMAIL";
From: $from
To: $emailaddress
BCC: $notify_email
Subject: Welcome !
