Umm....yeah. What you have listed seems pretty darn good to me!  Possibly consider a secondary MX server, just in case.

Subject: System Sizing

Looking for some pointers on sizing a machine to run Spam Assassin on. 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.

 

Thought and comments welcome,
