Exim using different HELOs on the same outgoing IP

[urgido]

Hello
Is this problem fixed? I have too problems with SPAMHAUS.
I have more than 15 accounts with addon domains with each dedicated ip so, if I disable "Send mail from account's dedicated IP address" and use the "Reference /etc/mailhelo and /etc/mailips" options, these files are empty and I need to do it manually that is a hard task.

Sorry for my bad english.

Hello

Internal case CPANEL-5340 is open to discuss potential changes to the current behavior of generating a 1:MANY HELO relationship in /etc/mailhelo when "Send mail from account’s dedicated IP address" is enabled, and multiple resellers exist on the main shared IP address, and when that IP address is not the same as the "main routed IP". It also applies to the case you mentioned where separate IP addresses are assigned to addon domain names associated with the same account.

The current workaround is to disable "Send mail from account’s dedicated IP address" and manually manage the /etc/mailips and /etc/mailhelo files as per the document at:

How to Configure Exim's Outgoing IP Address - cPanel Knowledge Base - cPanel Documentation

There's no update to report on this case at this time, but I will update this thread with additional information as it becomes available.

Thank you.

*: domainone.com
*: domaintwo.com
So, when an account sends an email from some addon domain of any of two accounts mentioned above this will delivered by the dedicated IP listed in /etc/mailhelo and /etc/mailips?

You can define the specific IP address a domain name uses when sending email in the /etc/mailips file. You would enter the specific IP address instead of the asterisk. EX:

example.net: 192.168.0.3
example.com: 192.168.0.3

The /etc/mailhelo file would look like this if you wanted to configure the hostname as the HELO address for specific domain names:

example.net: hostname.example.com
example.com: hostname.example.com

Or, you could use an entry like this to configure the same HELO name for all domain names or any domain names not already defined in the file:

*: hostname.example.com

Thank you.

Hi,
thanks for the clarification. I have latest question: Do I need to set addon domains and subdomains into these files?

thanks for the clarification. I have latest question: Do I need to set addon domains and subdomains into these files?

It's not required, but any domain name that's not defined in these files will revert to the default entry you have configured. For instance, using the example in my last response, any addon domain name that you don't configure would revert to what's configured next to the asterisks:

*: hostname.example.com

Let me know if this explanation helps.

Thank you.

Michael,

Yeah, probably the ticket was mine .

This is my tip to anyone facing this issue (thanks to Trevor Bordner), is this script: https://forums.cpanel.net/threads/how-to-script-etc-mailhelo-to-always-match-reverse-dns.444302/

Hello,

To update, cPanel version 72 will include a resolution (#CPANEL-18859) that ensure a reseller owned user sharing the reseller IP address has the correct entries in the /etc/mailhelo and /etc/mailips files.

Thank you.

Update: This is also fixed in cPanel & WHM Version 70:

Fixed case CPANEL-17899: Ensure /etc/mailips and /etc/mailhelo are updated on account add/remove.
