Pardon me, but no software or method is good or bad or "definitive" by itself. It depends on what YOU make it do. Greylisting is great when done intelligently. You save lot of DNS queries (unless you have every list rsynced) and unnecessary spam/virus checks when you do it first for suspicious hosts. Not blindly every host, at minimum use dnswl and auto-whitelisting. It even gives you time for network checks to catch up before retries. No matter what you use, research things and use your brains. Thank you.
