Re: X-Originating-IP

No, you cannot rely on that.

If you receive the mail from hotmail or yahoo, then the top "X-Originating-IP:" appears to be accurate. But I have seen mail with more than one of these headers, and the ones not added by yahoo or hotmail were forged by the spammer.

The basic principle of examining headers:
•You can trust headers added by your own server (or your ISP server)•If those headers show that the mail was received from a trusted site (a site that you trust), then you can also rely on the headers added by that trusted site.
Be suspicious of anything else.
