I ask because I saw this as a result of a header_check match:
May 12 09:47:00 mail postfix/smtpd[10013]: 696F12BC36: client=spiteful.cnc.net[207.155.249.209] May 12 09:47:00 mail postfix/cleanup[10034]: 696F12BC36: reject: header Received: from 123.44.167.190.d.dyn.codetel.net.do (123.44.167.190.d.dyn.codetel.net.do [190.167.44.123])??by spiteful.cnc.net (ConcentricHost(4.0.r15719) MX) with ESMTP id 5BAFB3F9A5.10ULC2UQ0B00;??W from spiteful.cnc.net[207.155.249.209]; from=<operators...@rhythmism.com> to=<x...@yyyy.tld> proto=ESMTP helo=<spiteful.cnc.net>: 5.7.1 Failed header check
Or do header_check rejections occur as part of the same SMTP connection that invoked them so my server never fully accepted their junk? E.g. no new, separate email fired off that might get me blacklisted?
