The Received: headers should contain this information already. For example in your message: Received: from mail.apache.org (hermes.apache.org [140.211.11.2]) by joseki.proulx.com (Postfix) with SMTP id BAA61FA63 for <[EMAIL PROTECTED]>; Thu, 16 Aug 2007 18:33:21 -0600 (MDT) ... Received: from [69.50.231.8] (HELO darwin.ctyme.com) (69.50.231.8) by apache.org (qpsmtpd/0.29) with ESMTP; Fri, 17 Aug 2007 00:33:15 +0000 However additional headers may be added using PREPEND in a check_recipient rule. http://www.postfix.org/header_checks.5.html Bob
