We are developing a product for exchange, I would like to know some details about exchange in the realtime usage. Since I am more familiar with Linux and not much aware of exchange (may be coz it is not open source)
1. In the realtime, is exchange server will open only port 25 for mail services or how is that.
2. I think to install exchange IIS should be running then port 80 should be open (guess ....)
Can experts write their views..
