hi! i'm getting daily emails containing rather pointless paragraphs of nonesense on 2 of my email accounts. the only thing they all have in common is they include a URL that ends with .cn

i tried to apply a filter to the body of the emails that would automatically trash any email containing .cn but it's not working, i'm sure because i did something wrong. since the .cn is part of a URL, is there a wildcard character that i should be using insteas of just .cn?

thank you for your time.
