 How much mail are you processing? You should be able to handle quite a bit of messages with a server like that. Is your IDE drive connected via SATA?

 A quick test might be to test the read/write performance of the drive during off-hours and during your peak hours to see how much of a deviation occurs between the two.



 Although it's probably not the answer you want, you should see a performance boost by moving to a 2.6 based kernel (I'd personally recommend either CentOS or Tao for the task). I definitely noticed an overall system performance boost after migrating my servers to one of the newer RHEL4 rebuilds.


 Cheers,
