While doing some research on making LN Address available on the domains of customers of @npub1lhufm... I came to the conclusion it's quite easy to do so in general. If you run a Wordpress site you can do it easily with a WoS address for example.

1. Install a redirect plugin, for example wordpress.org/plugins/simple…
2. Setup a redirect as on the image below.

You can receive now sats on lightning address: pay@<your domain>.com which redirect directly to the #walletofsatoshi lightning address of @npub1lhufm... (lncheckout)

If you have your own domain and you can fix the redirect in another way, you can do it without wordpress as well.
