Hello people. I have an interesting scenario to share and ask for some advice.

I have two cPanel VPS's, right? One of them is in a server node which IP range have been blocked in Spamhaus due to a bloody neighbour practicing spam. And this VPS of mine in the listed server is the one with more mission critical websites.
I cannot move those websites off to my second VPS because they serve too many features to several companies by IP. But, those companies are receiving bounces when it comes to send something as basic as a feedback mail to a yahoo address.

So the ask for advice is about this, what do you suggest to do, in order to allow them sending emails with no bounces until Spamhaus delist the IP range? Maybe something with MX records? Maybe sth with DNS clustering?

What would you do?

Any ideas will be thankful. Thanks!

Well, nope. Spamhaus have blocked the entire /24 range preemptively :(
I configured a parallel account in my other VPS with the same email accounts, and modified the MX records so they can be able to send and receive emails without having to move the entire domain. It's a provisional solution while Spamhaus decides to unblock the IP's
