Filters seem to not work

Hi

I keep getting spam emails from outlook.com and hotmail.com addresses. I went to Email settings >Mail Filter Rules >Add New rule. Without the quotes, I have "@outlook.com" in the Rule name field, and in the Sender from Contains under conditions, I have "@outlook.com". I have selected Reject With Reason, and simply have put "no email address". It's not working, as I continue to get emails from these addresses. Why? Thank you.
