Change email header from primary hostname to domain name?

[kishan giri]

Hi,
Fellow users, moderators, Staff Members, Linux admins... I need some help on Email headers.
I have tested my domain on mxtoolbox and saw smtp banner issue which I corrected after searching on cPanel Forum. Now I'm stuck on one issue. Kindly help me on this.

I have a domain = 24XXl.info with dedicated IP hosted with multiple domains with main shared ip and primary hostname= server.odeXXXXXXk.com.

I had made a test and below is the email header of it.

Received: from [127.0.0.1] (port=34192 helo=server.odeXXXXXXk.com) by server.odeXXXXXXk.com with esmtpsa (TLSv1.2:ECDHE-RSA-AES128-GCM-SHA256:128) (Exim 4.91) (envelope-from <[email protected]>) id 1fKUrc-0007e7-4O for [email protected]; Mon, 21 May 2018 01:53:32 +0530

What I want to do is to change on email header is to use My domain name = 24xxl.info or server.24XXl.info(PTR set to this) instead of server hostname = server.odeXXXXXXk.com in messageid , X-AntiAbuse, X-Get-Message-Sender-Via & X-Authenticated-Sender and also in other parts..
like

Received: from [127.0.0.1] (port=34192helo=server.odeXXXXXXk.com) by server.odeXXXXXXk.com

Received: from 82.102.xx.xx ([82.102.xx.xx]) by server.odeXXXXXXk.com (Horde Framework)

Can anyone please help me to set this .. I do not wish to use shared / main IP-address/hostname on my email header as it is being used by many domains.


NOTE: Server is VPS with root access so can edit any code if needed.

Thanks & Regards

By default when main shared IP is queried, the hostname if going to be recalled. If you do not wish to get this, you can use dedicated IP for your domain and it will query the dedicated IP and your domain name in the SMTP.

I have already changed the Exim configuration to use Dedicated IP instead of main ip ...
Problem is the header showing main hostname and I want to change it to sending domain

Hello @kishan giri

Setting the following will change the mailhelo to the domain (or whatever you set it to)

WHM>>Service Configuration>>Exim Configuration Manager

Reference /etc/mailhelo for outgoing SMTP HELO
Reference /etc/mailips for outgoing SMTP connections

since you have the PTR set to the domain name, setting the mailhelo to the domain should resolve any mismatch issues. I will point out that you may still receive errors if the PTR isn't a valid hostname like server.domain.tld


Thanks!
