Spam Email Headers
Posted on 2011-03-01
Guys, we have a constant SPAMMING issue, where someone within the organisation is spamming our mail server (its been ongoing for weeks now)
I have looked inside the header of the spam email and found the following
Received: from User by nepeaneng.com.au
with ESMTP id md50002621363.msg
for <email@example.com>; Wed, 02 Mar 2011 15:19:01 +1100

The valid account here is firstname.lastname@example.org. I found his computer and turned it off. Still the spamming continues. How do I rid myself of this nuisence? If thats the email that it is using to drop its payload, why is it when I kill his local lan access, the spamming persists?
email@example.com is the email sender that is spoofing
Any help would be appreciated.
