I have started getting emails with a domain such as "sfheh.horrorbracket.com" where the first part is never the same twice but the last 2 components are standard. Is there a way of blocking these in the junk email options. I have tried "horrorbracket.com" and "*.horrorbracket.com" but neither seems to work
