I don't use that restriction because there seem to be too many legit hosts that fail, and not enough bad ones that do. Don't forget you can use a restriction with warn_if_reject to get an idea of what it does for a while before you "go live" with it. Ultimately, anti-spam controls are quite site-specific. Listen to advice, then do what works best for you. -- Noel Jones
