Not really.
Most people are not perfect and cannot see the future. I'm sure the people
who had to make the decision were shown NTMail by some person who gained
commission for the same (and hence had a vested interest), convinced the
Telstra people that it would offer a better TCO than any other commercial
solution (orders of magnitude cheaper hardware and software etc.) etc. etc.
I'm sure even the preliminary load testing went to plan. It usually does.
Maintenance is something a lot harder to test for.
Why hang on? Because it costs a lot of money to change an installed system
- especially a mail server that >100,000 people use. The longer you wait
the cheaper the hardware becomes so you have to plan for a point where you
minimise your losses by changing.
