More than you want to know I'm sure. Every piece of E-mail sent out has a header that contains lots
of stuff about who it is going to and where it came from. The sending email client can place
anything in the following fields: 'TO:', 'FROM:', 'RETURN-PATH:', 'REPLY-TO:'.
The 'RECEIVED:' fields are added successively by The Mail servers that received and pass off mail to
each other. The last (top) one should be the mail server at your ISP
Here is an example:
From: "Comp. #389FD - 493A" <
[email protected]> To: <
[email protected]> Return-Path:
<
[email protected]> Received: from mx7.airmail.net from [209.196.77.104] by
mail2.iadfw.net (/\##/\ Smail3.1.30.16 #30.61) with esmtp for <
[email protected]> sender:

If you hit reply instead of placing the 'From:' into the 'To:' field of a new email, Your reply will
go to the address in the 'Reply-To:' field which can be different from the address in the 'From:'
Field. If a mail server can not deliver the mail to an address in the 'To:' field, then the mail
server will return a message to the address listed in the 'Return-Path:'
But who originated the message. Often this is unclear since spammers take advantage of mail servers
that still allow an 'open-relay' of anonymous mail clients. (The Mail Servers have to by nature
accept and pass on mail for other servers) In the example above the IP address of the servers in the
'Received:' is a clue. The last (top) one (209.196.77.104) is my ISP (Internet America in Dallas).
The next one is a public IP Since it has a Class A address
(4.42.203.141) The first one is a private IP (10.10.0.141) and is located somewhere behind a
firewall It has no direct access to the internet but must talk to a router that
passes IP packets out.
Most mail clients shield the user from the Header stuff. Some like Outlook make it particularly
difficult for the user to even see the header. For Outlook, in the message window, click on the menu
<VIEW><OPTIONS> to see the complete message header.
