Set 2 outgoing ips while sending mail for specific 2 domains

Hello,

Im looking for a solution that actually the exim mailinglist community did not answer about how to do it

As you know cPanel uses a file called /etc/domainips, inside this file you can add a ip with a domain name and when exim sends an email from that domain it will be delivering it using that specific IP. You can add many domains you want but just with one ip each domain.

What i would like to do is to use 2 ip's instead of just one.
How can i make exim to use 2 ip's for some specific domains (2 domains actually).

Is there any solution around to accomplish this?

I will pay your hourly work if necessary. Im really looking to do such a thing.

Any help will be highly appreciated.

Thank you.
