Actually, I'm not dead wrong. Tell me how many single boxes with
Exchange on them (you can throw as many processors as you'd like at
this) you have seen that can support a 100,000 user ISP community?

I saw a demo of Exchange on a HUGE Alpha box (4100, quad 466 mhz
processor...loads of memory [1 GB] ) that was using some pre-release
Exchange and NT software and it only supported 50,000 POP3 users and
1.8 million messages/day. As I've said, there are many Post.Office
sites out there supporting 50-100K plus users and, let's see, at
30msgs/second (which is low end with their new stuff) that would be
1.7 Million messages in a 16 hour period.

So, as far as scaling on a single platform, I guess these FACTS would
make you dead wrong wouldnt' it?


If you think Post.Office scales better than Exchange, you are dead

However there is no good way to do a price comparison, as an ISP
inevitably license Exchange in concurrent connection mode.

I am not advocating Exchange in an ISP environment, I am just curious
the cost comparison is.
