rDNS > and EHLO/HELOs do not match

[Florinpop]

Hello,
I had an dedicated server with cpanel administration. the hostname is vps.example.com. I have 3 ips with different RDNS for each one. 2 weeks ago ours ips get listed in the v4bl.org black list. they said that we need to fix the RDNS issue. We did it , we put the right rdns for each ip . When we cont the v4bl.org to delist us the respond that :

All IPs have been reprocessed and they all fail FCrDNS checks (Their rDNS
and EHLO/HELOs do not match):
xxx.xxx.xx.xx.x1 rDNS=*mail.example1.com <http://mail.example1.com>*EHLO/HELO=*vps.example.com http://vps.example.com>*
178.157.95.34 rDNS=*mail.example2.com <http://mail.example2.com>*EHLO/HELO=*vps.example.com <http://vps.example.com>*
178.157.95.35 rDNS=*mail.example3.com <http://mail.example3.com>*EHLO/HELO=*vps.example.com <http://vps.example.com>

On /http://multirbl.valli.org we made the FCrDNS test and we get ok everiwhere for all three ips.

I hope i was enaught explicite.

Is any posibility to fix this issue prom CPanel administration ?

What we need to do ?

From what you're describing, it seems that perhaps the rDNS needs to match the EHLO name. If the EHLO/HELO is vps.example.com, then your IPs should point to that hostname. If you want separate EHLOs for each domain, use /etc/mailhelo.

From where i can make this change /etc/mailhelo ?

 

[Florinpop]

Is enought to do only this part ?

Configuring Exim from WHM

or i need to do also the Creating and Editing the Appropriate Files , Editing /etc/mailhelo and Editing /etc/mailips ?

 

[vanessa]

SSH into the server and edit the files from there.

wright now in my vhm i have selected at "Send mail from account’s dedicated IP address " on.
if i turn off , "on" became availeble at 'Reference /etc/mailhelo for outgoing SMTP HELO" and "Reference /etc/mailips for outgoing SMTP connections" . Its enought to set "ön" or i still need to edit this two file ?

You still need to edit the /etc/mailhelo file - in fact, the setting you reference even says this outright. Either this, or simply use the same rDNS for all three IPs, and point them to the hostname of your server.

Hello

If "Send mail from account’s dedicated IP address" is selected, /usr/local/cpanel/scripts/updateuserdomains will be used to automatically populate /etc/mailhelo and /etc/mailips, overriding your changes. You can enable this option, and then run the command manually just for verification:

/usr/local/cpanel/scripts/updateuserdomains

Then, manually review /etc/mailhelo to ensure it has the correct entries.

Thank you.
