emails with no sender address

[mar53]

I'm trying to set up a rule to discard any emails with no address coming into my spam box. In the sender part I set does not contain and then  in the next box I put @ . After applying this no emails are coming in.  Can someone please tell me the correct procedure.

Why bother with a rule. If the emails are going into your spam folder then the spam filters are doing their job. Once in the spam folder just delete them.

Because I'm getting 60 + per day, also yo save me sifting through the list to ensure they are all spam
