I want to move mail with an empty subject to the junk folder. How can I search for an empty Subject? I have subject Contains, Doesn't Contain, is, isn't, begins with and ends with. If I configure a filter to: Contains "" (nothing) it moves everything to the junk folder.

Thanks for any help.

You can make a rule where the subject line does not contain any spaces. In the field following "Does Not Contain", simply press the space-bar once. It will caught all the blank subject lines. The only caveat is that it will also grab all subject lines that are only one word in length...
