I have a windows 2003 web server. I have the default windows POP3 Service installed that i am using to receive emails. I am also able to send emails via asp scripts using CDOSYS. However, i just dont know how to configure the damn SMTP service. CDOSYS seems to be working fine, but i cannot seem to use my servers SMTP service. I want to be able to give some of my clients a username and password that they can use to send emails via my SMTP service.
