Hi everybody. I'm facing with a small but annoying problem. All incoming e-mails scanned by our amavis in ISPConfig3 server comes with extra headers similar to: Received: from localhost (isp.mydomain.it [127.0.0.1]) by isp.mydomain.it (Postfix) with ESMTP id 4D8849EA45C; Fri, 11 May 2012 15:30:21 +0200 (CEST) X-Virus-Scanned: Debian amavisd-new at isp.mydomain.it Received: from isp.mydomain.it ([127.0.0.1]) by localhost (isp.mydomain.it [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id lfYFR3D03r86; Fri, 11 May 2012 15:30:21 +0200 (CEST) Of course, these are added by amavis when it receive the email to scan and by postfix when the email re-enters after scanning. These actions are performed via localhost (127.0.0.1) ports. Nothing strange. The problem is that forwarding these e-mail to other mail servers, sometimes are classified as spam because of "localhost" in headers. I've been googleing a lot to find a solutions, but most of teh strategies sorted no effect. In details, adding $allowed_added_header_fields{lc('Received: from localhost')} = 0; to amavis configuration file (ie in /etc/amavis/conf.d/50-user) seems to be ignored. Also, adding /^Received: from localhost/ IGNORE to /etc/postfix/headers_check seems to have any effect. Can anyone point me in the right direction to avoid that headers? Many thanks g
