How do I block unqualified remote senders? I know an empty return-path (<>)should be allowed. :-( I use qmail-1.03 with rblsmtpd + qmail-1.03-mfcheck.3.patch. I get bounces like this in my postmaster maildir: Return-Path: <WealthNet2000> Received: (qmail 58006 invoked from network); 10 Mar 2000 14:42:36 -0000 Received: from cr944640-a.brntfd1.on.wave.home.com (HELO mailer1.wealthnet2000.com) (24.112.103.150) by mail.net.uni-c.dk with SMTP; 10 Mar 2000 14:42:36 -0000 From: <WealthNet2000> To: <[EMAIL PROTECTED]> Date: Fri, 10 Mar 2000 05:22:18 Message-Id: <[EMAIL PROTECTED]> Subject: EARN $100,000 PER YEAR SENDING E-MAIL!!!!
