Look at the full headers - the "From:" and "To:" fields can be easily forged. The first Received: header should identify the system that delivered the mail to you, and the address it was to be delivered to. It also lists the address that was given when the mail was sent, but this can also be forged. An example, from the mail I am replying to: >Received: from x35.xmailserver.org (208.129.208.51:32842) > by arisiasoft.com with [XMail 1.16 (Win32/Ix86) ESMTP Server] > id <SA1E40> for <[EMAIL PROTECTED]> from > <[EMAIL PROTECTED]>; > Fri, 19 Sep 2003 22:18:56 -0400 Note that I received the mail from "x35.xmailserver.org", with IP address 208.129.208.51. It was to be delivered to "<[EMAIL PROTECTED]>", and the original sender claimed that they were "<[EMAIL PROTECTED]>". Note that this information is *not* the same as is contained in the message itself, which appears as: >From: "Nick Marino" <[EMAIL PROTECTED]> >To: <[EMAIL PROTECTED]> >Subject: [xmail] Un-wanted emails. - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
