If you built a new mail server today, for a fixed budget, what would be your priority on the following choices:
multiple CPUs higher CPU speed more RAM faster RAM more disk space faster disk drives
Our company went through this process a couple of years ago, but it seems to me that choices have changed, and that the requirements might be different. For example, would dual Xeons be that much better than a single P4 at a higher frequency?
Every mail server needs fast disks, preferably at least two, on two separate controllers, and the disk partitioning and allocation done carefully.
Then RAM, probably 1 GB minimum for an Imail + friends setup.
If you plan to do content scanning and lots of webmail, then you more CPU.
but NOTHING is going to work right, not quadruple 3.2 GHz CPU, not 800 MHz FSB RAM if you get the disk wrong.
The pressure and $$$ on the mail server can be dramatically reduced by using a separate, medium power box as MX.
