Mail servers, of necessity, _do_ use unique IPs, whether v4 or v6. > By implication they'd be unspoofable, > though I'm not sure I believe that. If you want to learn more about IPv6, I suggest "IPv6 Essentials" by Silvia Hagen, pub. by O'Reilly & Assoc. You can always spoof an IP address of any type. The only email header you can trust absolutely is the topmost Received header in an email. This address can't be spoofed. If it were, it would have been technically impossible to send the email. -- Lindsay Haisley | "Everything works | Accredited FMP Computer Services | if you let it" | by the 512-259-1190 | (The Roadie) | Austin Better http://www.fmp.com | | Business Bureau
