It is extremely easy to spoof, but google has taken steps to make it easy for mail servers to detect if mail is spoofed. So if you send mail from "google.com" without it coming from your network, than any server making use of SPF (Sender Policy Framewokr) would immediately identify it as a spoof, and will be blocked. To learn more about this system, see http://www.openspf.org/ > Anyway, it's not something I'm overly worried > about; I'm just not clear on what I SHOULD be using for hostname and > domain. Well, what is a hostname for the machine that is sending the mail. Since you are now going through your ISPs mailserver, it doesn't need to be a hostname that can be looked up. So something like mailout.my.dom.ain should do fine. Use your real domain for the my.dom.ain part. The more correct information you provide, the less mail from your system will look like spam. But even "localhost.local" would be OK (though a useful domain name would be better). Using "google.com" would make it look like you are up to no good. -j -- Jeffrey Goldberg http://www.goldmark.org/jeff/
