What e-mail server to use other than MS Exchange?
I am quite a newbie when it comes to running linux in server environments, but i have been quite succesfull in implementing linux (Mandrake mostly) as web, file and DC servers.
Now I would like to switch over to linux for my e-mail servers as well. I run a business where most of my clients are a bit stingy (understatement) and don't really want to pay the costly and highly overpriced M$ prices.
Most of them have been using MS Exchange, and like the functionality it provides with regards to: Well, basically everything.
Is there a li(u)nix based server app that i can use that will provide the same client/server (groupware) type of environment, and wich will provide for MS Outlook as a client?
Links would be greatly appreciated?!?!?!
