mutt is my MUA.

Currently I have 4,924 assorted messages in ~/Mail/in-Full-Disclosure.

Sorting by size, and picking a familiar size range, we see:

Without exception, these are all virii-laden. Whether they got here by
malice or by chance, they all contain the following:

Received: from NETSYS.COM (localhost [127.0.0.1])
 by netsys.com (8.11.6p2-2003-09-16/8.11.6) with ESMTP id i2H1kI327175;
 Tue, 16 Mar 2004 20:46:18 -0500 (EST)

in the "Received: " sequence immediately following the two examples
below, varying only in the date and timestamp, and ESMPT id.


Comparing one virus to one known list member (http-equiv -- sorry!) we
can see an obvious forgery:

Received: from excite.com (dt083n7c.san.rr.com [204.210.26.124])
 by netsys.com (8.11.6p2-2003-09-16/8.11.6) with ESMTP id i0QMicU18817
 for <full-disclosure@...ts.netsys.com>; Mon, 26 Jan 2004 17:44:39 -0500

versus a presumable "real" post:

Received: from mailrelay.megawebservers.com
 (mailrelay1-2.megawebservers.com [216.251.35.241])
 by netsys.com (8.11.6p2-2003-09-16/8.11.6) with ESMTP id i0R01gU17220
 for <full-disclosure@...ts.netsys.com>; Mon, 26 Jan 2004 19:01:43 -0500


What does this tell us? Virii are getting out via the list; whether
they are being transmitted inadvertently or deliberately is still open
to question...
