Some obvious choices I think would be to double the memory and move the spool and user accounts to a different disk. Defragmenting would not be a bad idea either, and of course there's a lot of even faster setups with the disks, but this will give you a lot of bang for the buck.
When I installed IMail 8, I found the anti-spam stuff to be a real dog, and it was hard to shut off. If you are using this with IMail, consider Declude JunkMail, a standard version will do better and do it more efficiently. If you want no spam blocking, then make sure everything is turned off and empty all the anti-spam files that come with IMail. Sometimes the files are marked as read-only on the drive and IMail tells you that they have been disabled when you apply, but they reappear when you refresh.
Another thing to think about before getting another server and software license would be to hand off the outgoing delivery work to a separate server, either a cheap Linux box, or just simply MS SMTP running on a different machine on your local network.

Server only runs Imail, No external Anti-spam nor Anti-Virus.
That is very strange. The dual 1.13GHz processor should be able to handle at least double your current load without high CPU usage (with spam and virus scanning). So without spam or virus scanning, you shouldn't be seeing 90% CPU usage.
I'm not sure what in the Queue manager or SMTP could be causing such high CPU usage -- perhaps someone else on the list will come up with some suggestions of things to look for that may help determine why it is so high.
