I've always enjoyed working with MDaemon from Alt-N. They've got what they call their Outlook Connector that allows for Exchange-like functionality from their software. It's pretty powerful with great spam tools built into it as well which is one of the many reasons I've stayed with them over the years. MDaemon is available at http://www.altn.com/Products/MessagingSolutions/MDaemon/.

I've heard and read about Zimbra, as well as a few others like Merak Mail Server, just wondering what, if any, is used on campus. -- Troy D Murray
