Possibly running in RAID configuration) will give better results when there are Have at least 2 disk drives in the server. If you are going to host more than few hundred mailboxes, I would suggest you Availability of updates is a very important security consideration. This is a largeĬontrast to CentOS which is based on RHEL where you have updates available for Not be able to get any more mainstream RPM updates for FC3. So for example if the current version is FC5, you will soon Typically updates are only available for the previous-to-current Each Fedora Core release only includes a very short period of update.You want at least MySQL v4 as so you have access to some important performance improvements Use at least Fedora Core 4, as this gives you MySQL v4.You are going to use Fedora there are a few things you need to be aware of : This guide will workįine on Fedora as well, with no changes required to the installation steps.
