Hmm. OK, I do not see my home IP address in any mail header (and yes, I use submission and that is the only way to send mail from my server), nor do i see the helo hostname. These are the received headers from a message I sent to an iCloud account I have: Received: from mr28p00im-smtpin039.mac.com ([17.110.71.38]) by ms20521.mac.com (Oracle Communications Messaging Server 8.0.1.3.20170906 64bit (built Sep 6 2017)) with ESMTP id <0p85003x1u2a9...@ms20521.mac.com> for *user*@icloud.com; Thu, 03 May 2018 16:06:10 +0000 (GMT) Original-recipient: rfc822;*user*@icloud.com Received: from mail.covisp.net (www.covisp.net [65.121.55.45]) by mr28p00im-smtpin039.me.com (Oracle Communications Messaging Server 8.0.1.2.20170607 64bit (built Jun 7 2017)) with ESMTPS id <0p8500evtu27d...@mr28p00im-smtpin039.me.com> for *user*@icloud.com (ORCPT *user*@icloud.com); Thu, 03 May 2018 16:06:10 +0000 (GMT) Received-SPF: pass (mr21p00im-spfmilter008.me.com: domain of kr...@kreme.com designates 65.121.55.45 as permitted sender) receiver=mr21p00im-spfmilter008.me.com; client-ip=65.121.55.45; helo=mail.covisp.net; envelope-from=kr...@kreme.com I also tried it with a local domain to another local domain, sending to a gmail address, and sending from an iCloud account to gmail (don't think this would involve postfix at all). In none of these where my home IP or helo name or user login name included in the headers. Now I wonder why? -- "Is that a star?" "Nah, that's Ted Danson."
