However -- the majority of the filthy spam that I receive comes from AOL! So take that mr. corporate giant.
No, it doesn't.
Let's say you get a piece of spam from "g1antpen1s@aol.com". Does that mean the spam came from AOL?
No. The From: address is forged. It is so easy to do, anyone can do it in under two minutes. If you like, i can send you an email that comes from; god@heaven.com or From: kimmer@techsurvivors.com or From: billg@microsoft.com or From: anything else I want. It's called "spoofing." All spammers do it.
Never, ever trust the From: address you see in any email! Just because it says From: someone@aol.com, that does not mean it came from AOL. AOL has very strict mail server control software that does an excellent job at stopping spammers.
The only way to tell where a message
really came from is to look at the full headers. You will see a bunch of lines that start with "Received: from". After the "Received: from" will be information about the IP address and mail server the message came from.
Here is an example of a piece of spam I got that supposedly came from AOL. The headers say:
Received: from rly-xk04.mx.aol.com (rly-xk04.mail.aol.com [172.20.83.41]) by air-xk01.mail.aol.com (v95.1) with ESMTP id MAILINXK14-5953f26dcbf11f; Tue, 29 Jul 2003 16:45:44 -0400

You look at the LAST Received: from line. In this case it says:
Received: from compuserve.com (209-130-218-13.nas1.roc.ny.frontiernet.net [209.130.218.13]) by rly-xk04.mx.aol.com (v95.1) with ESMTP id MAILRELAYINXK49-5953f26dcbf11f
In this case, what it is telling you is that the computer the message came from had IP address 209.130.218.13.
IP address 209.130.218.13 is owned by an ISP called frontiernet.net, who in turn gets their service from Global Crossing. So even though the message says it was from 46IHEI0E63K3438E@aol.com, it was not. It actually came from a spammer who was using Global Crossing,
not AOL.
