CPU is important, but not as important as you might think. A single P4
2.0GHz can handle more than 100K messages/day if the rest of the system is
balanced. Don't go for that quad-processor 3.2GHz Xeon system with 4MB
on-die cache with 8 SCSI disks in a RAID 0+1 array, 32GB RAM and dual
gig-Ethernet NICs unless you're trying to figure out how to push a million
messages/day through one box. Frankly it'll be cheaper to have a dozen 1u
P4 2.8GHz 40GB IDE systems than it would be to buy that one monster box ...
AND you'll have better reliability with a dozen expendable boxes.
Greylisting becomes slightly more interesting over a dozen boxes, you better
know (or learn) to use a real database system at that point.
Forget about xeons :)
Opteron has better marhitecture (64bit,numa ..etc) and bandwidth
