I have a upcoming demo of a product that (amongst other things) sends email alerts. I don't know if I'll have an Internet connection for this demo. I also need to be able to fire up something like Outlook Express and view these alerts.
So I have come to the conclusion that I need to install some sort of small mail server to send the mail and that I can then connect a mail client to.
Are there any tiny mail servers out there that will install on a windows 2003 server? I really need to smallest and thinnest possible as I got 100 other stuff running on the same development machine and I don't want to slow it down ever further ...
