[Declude.JunkMail] blocking spam faked as coming from local address

[Glenn \\ WCNet]

How do I reliably block this kind of thing?  Can my own domain be added to the SpamDomains list?  I've replaced the recipient address with [local-user] in the headers below, but it was the same valid local user account on all parameters.  138.89.104.227 is not one of my IPs.   Glenn Z.     Received: from wcnet.net [138.89.104.227] by wcnet.net with ESMTP (SMTPD32-7.15) id 04542B014C; Thu, 18 Sep 2003 23:04:21 -0500 Received: from kennedy-henry [192.168.1.101] by wcnet.net with MailMXPro2(2195.5631); Fri, 19 Sep 2003 00:04:20 -0400 Message-ID: <[EMAIL PROTECTED]> From: "jenna henny" <[EMAIL PROTECTED]> To: <[local-user]@wcnet.net> Subject: Spam (10) - Don't wait for rates to climb back up Date: Fri, 19 Sep 2003 00:04:20 -0400 MIME-Version: 1.0 Content-Type: text/html; charset="ISO-8859-1" X-Priority: 3 X-Mailer: mailer Return-Path: [local-user]@wcnet.net Abuse2-Tracking: <Z2xlbm5jbXpAd2NuZXQubmV0> X-Declude-Sender: [local-user]@wcnet.net [138.89.104.227] X-Declude-Spoolname: D8045042b014c3731.SMD X-Note-In: This E-mail was scanned on MAIL1 by Declude JunkMail for evidence of spam.
