I guess we can add PayPal to the list of major players with poorly configured DNS: $ host 206.165.243.120 120.243.165.206.in-addr.arpa domain name pointer email-120.paypal.com. $ host email-120.paypal.com Host email-120.paypal.com not found: 3(NXDOMAIN) It's surprising that PayPal, the target of so many phishing exploits, doesn't have squeaky clean DNS configured for its mail servers.
