I think that's a pretty safe rule of thumb: moving from Unix-based to 
MS-based solutions tends to be a step backwards (for all parties 
involved but MS.) :)

I run numerous small-business mail servers on Linux. I cannot imagine 
doing that without BIND running on the same machine, as spam-checking 
requires many DNS lookups. I heard some time back that MS Exchange does 
not work with a nameserver on the same machine! What a mess.
