Have you tried a qmail toaster w/PHP management system. The toaster easily blows exchange's mail functions out of the water, but to get the more advanced features you need a good php programmer. I run windows box on the network but even our 2000 webhosting has the DNS and mail on UNIX. I have managed to hack our webbased mail and contact manaement pages into my outlook2000/2002 so they appear as just another folder in Outlook but they display the webpages of my choice.
