We began to receive tons of spam messages that have empty "from" or "sender" field and we can't seem to get the Message filters to trigger on the empty fields.

I am trying to create a filter that will remove messages that pass through any information in the FROM or SENDER fields.

I tried: 'contains + [EMPTY]' and ' sender contains ++ [EMPTY] "(where [WHITE] is leave this field empty), and it does not work.

The filter I use is like this:
Does not contain a @.
If this line is empty there is no symbol @, but otherwise he will have this symbol, since each email address there.
You could do the same for the sender line.
