The list server re-mangles the internet headers and only shows it as the source. If you look at the internet headers of this email you will see the list server as the source , even tho it originated from nrc86.nrc.govt.nz via our firewall relay.
The list server does keep the x-message-ID , which will have a local reference (to the users domain) to the originating server. E.G. X-Message-Id: <[EMAIL PROTECTED]> At the end of the day the list server will have a full copy of the spoofed messages sent, so if you feel aggrieved, email [EMAIL PROTECTED] and they can deal to the spammer/childthing -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Eric Fretz Sent: Thursday, 2 June 2005 9:46 a.m. To: Exchange Discussions Subject: RE: Spoofing the exchange discussions list server The spoofed messages came from intm-dl.sparklist.com [64.62.197.83], which is the legit list server. While I agree that SMTP (RFC2821) and Message Format (RFC2822) both leave a lot to be desired, this does not appear to be a simple SMTP header spoof. I even went back and scoured my firewall logs to see what MX was connected to my MX at the time the message was sent. The message did actually come from the Exchange Discussions list server. <insert twilight zone music here> Eric -----Original Message----- From: Chris Scharff [mailto:[EMAIL PROTECTED] Sent: Wednesday, June 01, 2005 3:06 PM To: Exchange Discussions Subject: RE: Spoofing the exchange discussions list server They read RFC2821 and RFC2822? > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On > Behalf Of Eric Fretz > Posted At: Wednesday, June 01, 2005 2:49 PM > Posted To: swynk > Conversation: Spoofing the exchange discussions list server > Subject: Spoofing the exchange discussions list server > > > Has anyone figured out how the perp spoofed e-mail messages > to the list and impersonated Ed Crowley and others?
