In the Deliverability War Stories presentation Craig Spiezle, Director of Online Safety Strategies and Technologies at Microsoft, speaks about the importance of reputation. In one example Craig

we do deliver that mail? No we do not." Obviously, paying attention to the reputation of IP address is important.
