How does a message beat the filter?

I filter messages to a specified junk folder if the sender is not in my address book as described here: https://support.mozilla.org/en-US/questions/1274703 So far it has worked perfectly.

However, ONE message got through the filter today and it is a mystery. The sender is exactly this: "Robert Eugene" <> but there is a reply-to of this: christhorson150@outlook.com Neither is in my address book. Please see the attachment for the massage source. Can anyone guess how it did it? I'll be happy to provide additional details.

The From: header doesn't contain an email address, so the filter probably can't decide if it's in your address book or not. I think you could filter on these 'empty' senders by adding a rule as in the attached picture.

Thank you for the quick reply. In your image, I can't decipher the symbol after "Doesn't contain"; what is it?

When I select "Doesn't contain" I have a blank text box.

Click in the box and enter some text. My picture shows the @ symbol which an empty address will not contain.

An @ as all mail addresses contain one. If it does not contain one, it is really malformed and your provider should be dropping it into spam. Especially as the To does not contain a valid address either, delivery being managed via BCC.

I note that this is a newsletter that conforms to SPF so the sender is legitimate and it identifies it's self a BULK. Why not just ask the sender to stop sending you mail.
