I work in a very small company. Right now we are running a windows server on a standard old dell PC. Today the owner asked me to start looking into potentially moving to OS-X Server as our primary server for the company. I was thinking we could just get the Mac Mini Server edition and use that. How much work to set it up as our primary file server? ... as our web server? ... as our email server? We have several external 2TB drives to share, no big deal there; but we also need to have VPN access of some type. We have a decent linksys router that will setup the VPN tunnel, just need to make sure we can get access to our data. We want to move our web server away from a hosting company we are using now, along with our email because some of our email is "sensitive" and thus we want to keep it on our servers more then someone elses. One of the reasons to use OSx Server is because it isn't as popular as Windows Server and thus less attacks target it. I know OSX when setup right, is quite secure, but how about OSX Server, is it better then Windows Server or are they about the same now? Mail, does OSX Server have something compatible to Exchange? Does it have problems with some email attachments (winmail.dat)? Another thought, of his, not mine, was that he found he could get a G5 XServer (or multiple) for almost nothing ($200 each) and run those instead of Intel based servers because they are less likely to be susceptible to buffer overflow attacks. I don't like the idea of running old hardware, but the price is right. Any thoughts on this? Any ideas? Sorry if much of this has already been covered; and any links to places where I can learn more about this would be helpful and appreciated. Thank you!
