Are message IDs assigned by each MTA to handle a given email? As in:

Received: from smtp01.infoave.net ([165.166.0.26] verified)
  by mail.MDCCLXXVI.com (Stalker SMTP Server 1.8b9d14)
  with ESMTP id S.0003132321 for <Joe@Blow.com>; Sat, 23 Aug 2003 08:45:36 -0700
Received: from TRAVELER ([209.164.228.118])

 with ESMTP id <01KZST178D2Q993D37@SMTP00.InfoAve.Net> for Joe@Blow.com; Sat,

If so, then given:

Received: from [209.194.92.34] (HELO ARLSAUCER)
  by mail.MDCCLXXVI.com (Stalker SMTP Server 1.8b9d14)
  with ESMTP id S.0003181674 for <Joe@Blow.com>; Sat, 30 Aug 2003 07:40:54 -0700

is it safe to assume that 209.194.92.34 is the originating host and not a relay?

209.194.92.34 has been belching out sobig virus laden email and I've been the recipient. There's no PTR record for this host, which tends to make me think it's a workstation, not a mail server.

Just trying to figure out how to email the doofus responsible.
