I'm using a Dell PowerEdge server with Xeon 3G w/1G DIMM RHEL 4ES. Zimbra install is the only thing that will be used.
With less that 20 mailboxes I have been told that this is on the LOW side of acceptable. What upgrades would make Zimbra work well? Or, could you describe an "acceptable" configuration that functions correctly?
If this passes our impression tests, I would like to install the licensed version but I am fearful that we may not be giving it a proper test.
