Email marked as SPAM by Google and Microsoft

Hello! I've been struggling for quite some time with a specific email server setup based on a cPanel. For some reason emails sent out from this specific server are being marked as spam and delivered to spam/junk folders of Gmail and Outlook. Can somebody with bigger experience please have a look at my current configurations and maybe point out any flaws in the setup or give a hint as to what to look for? IP addresses at disposal: x.x.x.127/27 cPanel installed on: x.x.x.99 Domains added to WHM on x.x.x.99-105 In order not to disclose the domain names, I won't be able to provide exact domain names, sorry. Emails are being marked as spam when sending from x.x.x.99-105 by either web interface and using email clients. SPF, DKIM, MX, PTR entries are valid. Domains and IP addresses is not within blacklist check that mxtoolbox.com website offers. Mail-tester.com results: 8.1/10, main points off have gone from PYZOR_CHECK (-1.985). The message it provides is: Similar message reported on Pyzor (Whitelist - Pyzor) Microsoft SNDS does not provide reasons for being marked as spam from what I can see. Microsoft support does not provide information on how to proceed with issue fixing. Google Postmaster does not provide reasons for being marked as spam from what I can see. Google support does not reply on how to proceed with issue fixing. Additional information as per the "Guide To Opening An Effective Forums Thread": My access level is root administrator. Software versions: /etc/redhat-release:CentOS Linux release 7.2.1511 (Core) /usr/local/cpanel/version:11.58.0.28 /var/cpanel/envtype:standard CPANEL=release Server version: Apache/2.4.18 (Unix) Server built: Jun 10 2016 08:13:27 Cpanel::Easy::Apache v3.32.14 rev9999 PHP 5.5.36 (cli) (built: Jun 10 2016 08:15:50) Copyright (c) 1997-2015 The PHP Group Zend Engine v2.5.0, Copyright (c) 1998-2015 Zend Technologies mysql Ver 14.14 Distrib 5.6.31, for Linux (x86_64) using EditLine wrapper I've completely lost my mind, discovering this... Outlook.com support only sent us a link to the terms and conditions of their service. Google did not respond to a support query at all. I would be glad for any clue on where to search for a solution. Regards, Oleg Vasilyev

  Do you have RDNS configured at the hosting data centre ?

  Hello, It's possible the IP address already has a reputation for SPAM. Are you able to obtain an additional IP address with RDNS and see if the issue persists? There's a document on how to do this at: How to Configure the Exim Outgoing IP Address - cPanel Knowledge Base - cPanel Documentation Thank you.
