How to set an external ip for sending emails

I would like to know if it is possible to add a secondary (external) IP to use to send emails from my cpanel accounts.

My case:
Currently I run my server on the openstack platform and I can't add two IP's on the same network interface (eth0). I can only add if it is on separate interfaces (eth0 and eth1), however cpanel/whm cannot route this second interface (eth1).

In this case, I need to use an external IP to be able to use it as a backup in case the primary IP falls into a blacklist.

It's possible?
