Emailing on Windows XP/2000, was using winsock?

I recently have been writing a program that automatically needs to send out emails. Well I wrote alot of this program on a Win98 machine and used winsock for the emailing... Well what I did not realize even though I should of was that when I brought it to work winsock does not work anymore. Yep no more winsock, duh.. I forgot about raw sockets for a sec :) . I have windows xp pro for my dev station and the server that will be running this app is Windows 2000 server. Is there another simple solution to this? This needs to automatically send emails out so I cannot use outlook since it prompts the user to allow this or not. I would like not to have to spend any more money on this app since the budget is about maxed out. This is a VB5 app.:confused:
