Email From my cPanel server landing in JUNK Folder

I have upgraded to the latest version of cpanel as I try to solve an issue with email. At times an email which originates from the mail server powered by cpanel will end up in the JUNK folder of receipts mailboxes. As I try to figure out what might be causing the issue, I have requested specific individuals to send me the message headers of Outlook Program to try and self-diagnose what might be going on. I have 1 server that is the mail server for 8 domains with 1 being a national organization. I have spent the past 2 days educating leadership in this national organization that detection of emails landing in the junk folder is a result of the receiving end and not the sending end. I have looked over many articles that might relate to the issue in hopes that I can solve this. One online test shows the PTR Record not matching and cpanel reports: The system sends "*****.org""s outgoing email from the "45.76.xxx.xxx" IP address. The only PTR value for this IP address must be "*****.org". This is the name that this server sends with SMTP"s "HELO" command to send "******.org""s outgoing email. 1 unexpected PTR value exists for this IP address:

• rns1.nameserver.com

To fix this problem, contact your system administrator and request that they replace all PTR records for ".in-addr.arpa" with the following record at "rns1.nameserver.com" and "rns2.nameserver.com": Suggestions as I have moved to cpanel from zimbra to try and keep up to date with technology processes

  PTR records can only be changed at the data center. There maybe a software tool for you to do this in your account with them, if not you will need to ask them to edit/create the rDNS (PTR) record for you.

  I'm not entirely sure I understand this statement entirely but if you're saying that email landing in junk is a result of issues on the receiving end not the sending end, that is not necessarily true. In order to ensure your mail stays out of spam you need to adhere to the best practices for mail servers. The documentation that follows goes over these:

  @kernow I fully understand what you said, but I think you may be unaware of the following: There are two methods - some providers delegate authority and allow you to add/modify these records on your server using instructions like those provided here: How to Configure Reverse DNS for BIND in WHM | cPanel & WHM Documentation The other would be through the use of a tool like what you're suggesting. Thank you.

  Not that it's needed, but to reaffirm what CPanelLauren is stating; I have complete DNS control on my server and set my own PTR records on the WHM DNS section. PTR can not be set in CPanel accounts but can be set in the WHM account. This may be what is causing Kernow's confusion(?). PTR records are not always "set in the data centre" but you can request the data centre (or IP provider) can give you the IP you need to correctly complete the PTR records on your own DNS.
