MailScanner on Exchange

[hermit921]

A risk assessment would be a nice idea.  Totally useless, though, and I am 
not supposed to spend time on such things: "The decision has been made".  A 
business needs assessment would be a good idea, too.

This is my first experience in how companies choose to use 
Exchange.  Hopefully my last.
