Got some spare hardware and want to put a store and forward email server at a second site as backup to cover times our exchange server loses net connectivity (or power this is Darwin).
Looking for opensource solution as I don't have the funding ATM to buy another windows server license.
Need something easy to setup and low maintenance as it will live in a office that rarely gets visited.
What have you used or would recommend?
I have little linux experience but am willing to spend sometime learning if you point me in the right direction.
