Shankar, I don't know if you still need help with this or not but I found the article again .. http://www.phpeasystep.com/phptu/23.html . It's just a simple little tutorial that tells you how to set up this mail server on your local machine (http://argosoft.com/rootpages/MailSe...T/Default.aspx) and gives you a little php script so you can test and see if it is working properly or not. Hope this helps.
