Woods" Subject: spammer problem - help! Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Sender: owner-freebsd-isp@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org X-To-Unsubscribe: mail to majordomo@FreeBSD.org "unsubscribe freebsd-isp" I have had a problem over the last month or so of someone using our mailer-daemon to send spam email to myself as well as users on our net. My sendmail is running on freebsd and I've applied all of the spammer patches that I can find. I've even added the hostname in the spammer db file but our system still accepts mail from him. How can I keep this guy and others from forging mail and making it look as though it is coming from my mailer-daemon? Here is the header from one he sent to my email address yesterday: --------------------------------------------------------- Return-Path: anitb@mail.t-1net.com Received: from mail.t-1net.com (root@1Cust182.tnt2.stafford.tx.da.uu.net [208.252.105.182]) by netgazer.net (8.8.5/8.7.3) with ESMTP id KAA03003 for ; Thu, 5 Feb 1998 10:22:21 GMT Date: Thu, 5 Feb 1998 09:41:31 -0600 Message-Id: <199802051541.JAA02876@mail.t-1net.com> From: MAILER-DAEMON@netgazer.net Subject: Low Cost Advertising X-UIDL: 6a53b1fd94536b2343668e60c04444de ---------------------------------------------------------- Thanks, in advance, and yes I have sent email to abuse@uu.net.
