You need to add it as your NIP05! Actually we are not very good as your lightning address, only nip05

Ah, got it! I now use it as nip-05!
By the way, when I setup my nodeless account, I failed to use borisbtc@lifpay.me as lightning address, so I used an address from wallet of satoshi. The site just didn't accept borisbtc@lifpay.me as lightning address...
Thanks for reporting we'll take a look!
