Uh, perhaps it's just me, but wouldn't it be smarter to plan for peak usage? Or do you not have that kind of info?

This server will be protecting 2 mail servers, one receives an average of 6 million messages a month, the other around a million. The send side is around the same but I'm assuming those number don't need to be considered for sizing an anti-spam server. I guess, that's if only inbound email is scanned and not outbound. The average hourly comes to about 173,000 messages, however there are hills and valleys throughout the day. My current thinking is a 2 CPU machine, either 2.2 GHZ Intel or 1.06 GHZ Sparc, that's expandable to 4 CPU's if necessary. 4 GB of RAM and some fast (10K RPM) SCSI drives on a dedicated RAID controller. On the same subject, I'm still trying to decice between Solaris and Linux for this machine. I don't want to start a religious war on this topic, however which would be the better performer for SA? I'd imagine that'd depend on the Perl deployed and how spamd is compiled as well.
