Hi, I'm trying to whitelist mail from sprintpcs.com in the best way possible, but it's ignoring attempts at even using whitelist_from and I don't know why. Perhaps it's something with the way the mail is formatted? No SPF or DKIM available to be used.
These messages are being quarantined because people are using sending photos in a quick text message without any subject or body content. I've put up an example here and hoped someone could take a look. http://pastebin.com/1vapSDdF This appears to be the only available headers: Received: from lxnsmsomta04.localdomain (smtp4a.mo.sprintpcs.com [66.1.208.13]) by mail01.example.com (Postfix) with ESMTP id 7FF846800CC30 for <mo...@example.com>; Sat, 25 Jun 2016 21:21:21 -0400 (EDT) Received: from musreb31.nmcc.sprintspectrum.com (unknown [10.25.157.71]) by lxnsmsomta04.localdomain (Postfix) with ESMTP id 64B18608C for <mo...@example.com>; Sat, 25 Jun 2016 20:19:20 -0500 (CDT) The envelope-from looks okay, but the "From" is not formatted properly. X-Envelope-From: <15556142...@pm.sprint.com> From: 5556142...@pm.sprint.com Thanks for any ideas. Alex
