I am developing mailing system for intranet. I need to know how to send and receive emails on intranet. This intranet would be used for office. All employess will have userid/email address on intranet. They should able to exchange email for their office use. I am using Windows XP, SQL server 2000, ASP, IIS 5.1 and VB script. I tried using CDONT component, but it does not work. Which mail server do I need to use? Do I have to install pop3 and SMTP webserver. Or SMTP server in IIS may help me with this...if anyone can guide me on this?
