In addition to the built-in console commands, you can create your own commands using the Lua function [msys.registerControl](/momentum/4/lua/ref-msys-register-control). If, for example, you have domains that are heavily throttled and discard messages that are over the limit, you can create a console command to push emails for these domains into the delayed queue:

<a name="operations.console.lua.registerControl"></a> 


```
require("msys.core");

local function delay_domain(cc)
  local domain = cc.argv[1];
  local dr = msys.core.dns_get_domain(domain);

  if dr ~= nil then
    print ("Domain delayed as requested");
    msys.core.mail_queue_delay_domain(dr, "451 4.4.1 [internal] manually delayed domain");
  end
end

msys.registerControl("delay_domain", delay_domain);
```

This code creates the ec_console command: **delay_domain *`domain`***           .
