<P><FONT SIZE=2>I would recommend you consider using DNS (mutliple equal preference mx records) to split the load over several lesser machines. I like Compaqs DL360's (hyperthreading processors work very well) and I've heard of other people on the list using them in the past. I think you would be safe putting your 100K msgs/hr load on 3 of these boxes if you want to be safe. Two might also do the job but you might get some delay during peak hours of operation. If you did build three boxes you might setup 2 to load balance and one to act as a failover. </FONT></P>
<P><FONT SIZE=2>A DL360 typically has dual 2.4Ghz (hyperthreading), 4GB ram, dual 40GB SCSI. I've found the hyperthreading Xeon processors to be far superior over non-hyperthreading procs. Definitely worth the investment. </FONT></P>
