While I\’m reading digg come a cross this link It\’s basically a Exchange alternative in Linux I haven\’t tried it, downloading as I type this but looks very interesting. Exchange 2007 have many features but comes with a heavy price. And competition is always good. might be ideal for small businesses. ![\"unison\"](\"http://www.unison.com/images/diagrams/architecture.gif\")
Any way I\’ll update it soon as I know try and use it on my Virtual machine
