Hello!

I appeal to your knowledge in search of the best ideas to answer the following two questions:
  1. As a provider of VPS servers (servers to which I do not have access), what would be the best method to limit the number of emails of each customer? (KVM virtualization via Proxmox, public IP addresses for each VPS)
  2. What would be a reasonable limit so that my IP addresses do not end up in blacklists?

Thanks!
