Blocking extensions?

I've noticed that a lot of the emails I get are from slightly different domain names, but they all have the same thing in common. They all come from a ".eu" domain address. Is there a way to make a message rule that says if I get any email that comes from a .eu address send it to spam? I see how to block specific website, but I want to block a blanket list of domains. On other sites I've done something like *.eu, that will block anything that ends in eu. Will this work here too?
