Why don't you unbind it from localhost and bind it to a specific 
interface that you have appropriate IPtables etc rules in place for?

-!- rspamd/local.d » cat worker-controller.inc
bind_socket = "192.168.x.y:11334";

But yea if you're letting your webhosting users use SSH to port forward, 
having rspamd open will soon be the least of your problems I'd suggest!
