<P><FONT SIZE=2>If I were implementing in this type of environment, I would break it up into more manageable chunks. First, figure out roughly how many messages are processed each day. If you are expecting 500,000 users who will receive on average 75 messages per day you are looking at about 37,500,000 messages per day (that's a lot of mail). You can build boxes fairly cheaply for handling a fraction of that mail, say 1,000,000 messages per day. Get yourself 40 boxes, some load balancing tools, a way to manage the configuration files easily and you are in business. There were some threads within the past 3 months about average load with hardware descriptions that you will find somewhat helpful. </FONT></P>
