Well, abuseat.org probably doesn't do that with a single server.

They probably do it like just about anyone else with more than a trivial
message volume, with multiple servers, possibly served by redundant
transparent load balancers and also possibly by using anycasting to
distribute their service cleverly based on geography.

What you see as mx.example.com with a single IP address may in reality be
dozens or hundreds of servers, spread across the globe.
