Enterprise scalability

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.
