x headers and Received from

[z3d3m0n]

Hello Community,

i have a x-headers and question
i am hosting mostly users with a dedicated IP's. they are complaining about the x headers and "Received from".

currenlty i have in my exim setting.
Send mail from the account’s IP address "On"
Use the reverse DNS entry for the mail HELO/EHLO if available "On"

what i want is to show the customer domain or rDNS e.g. domaincrm.com and not the hostname cpp.domain.cloud in X-Headders and "Received from"
change the $primary_hostname to $sender_address_domain ?
what should i change to complete the task?

i guess this is what i need

Change X Headers to allow for the host name to be set based on how exim is being connected to

As an administrator, I would like the X headers (X-AntiAbuse, X-Get-Message-Sender-Via, X-Authenticated-Sender) to use a variable that allows for the host

features.cpanel.net

has this feature been implemented?

Hey there! I don't see any action on that feature just yet. If we do take action on that, it'll get posted to that features page, so that is the best area to check in on.

@cPRex ,

thanks for reaching out.
i will check from time to time

meanwhile
i have managed to fix the x headers by modifying the /etc/exim.pl.local

 "X-AntiAbuse: This header was added to track abuse, please include it with any abuse report\n"
      . "X-AntiAbuse: Primary Hostname - $sender_address_domain\n"
      . "X-AntiAbuse: Original Domain - $original_domain\n"
      . "X-AntiAbuse: Originator/Caller UID/GID - [$originator_uid $originator_gid] / [$caller_uid $caller_gid]\n"
      . "X-AntiAbuse: Sender Address Domain - $sender_address_domain\n"
      . check_mail_permissions_headers() . "\n";

but i can't locate the "received_header_text" in the exim.conf or the Advanced section , do you know where to look?

 

[cPRex]

That one I'm not sure about - I do see that it's mentioned here:

14. Main configuration

Exim is a message transfer agent (MTA) developed at the University of Cambridge for use on Unix systems connected to the Internet.

www.exim.org

but it could just be something we aren't included on the cPanel side.

 

[z3d3m0n]

its' quite hidden) i have managed to locate and change it when you click on the blue "Advanced button" in Exim configuration manager a drop-down will pop up "received_header_text" than you just need to change a variable to an appropriate one, and done...

 

[cPRex]

Nice! Hopefully this thread will help others searching for this variable in the future!

 

[z3d3m0n]

The only thing I have not solved yet is how to save the /etc/exim.pl.local permanently, it's getting rewritten every time I change the Exim configuration via WHM

 

[cPRex]

After you make the change, have you tried running these commands?

/scripts/buildeximconf
/scripts/restartsrv_exim --restart

 

[z3d3m0n]

after i have run

/scripts/buildeximconf
/scripts/restartsrv_exim --restart

it simply overrode my /etc/exim.pl.local , any other ideas?
thx

I don't have any additional ideas on my end. If you'd like to submit a ticket our team may be able to recommend additional steps, but our support for those types of customizations is a bit limited, I'm afraid.
