And yes, this is already possible. Just select all servers from the sidebar, then head to Tools & Utilities → Spam AutoShield Tools. From there, you can block (or whitelist) domains, IPs, or specific email addresses across all your servers with one click.
Tip: it's optimized for large clusters (100+ servers), so feel free to leave the window open and continue working in another tab , the operation might take a little while to complete across all servers in large clusters.
