We just started receiving tons of spam messages that have empty "from" or "sender" fields and we cannot seem to get Message Filters to trigger on empty fields.

I'm trying to create a filter that will delete messages that come through without any information in the FROM or SENDER fields.

I've tried: "From + Contains + [BLANK]" and "Sender + Contains + [BLANK]" (where [BLANK] is leaving that field empty), and it does not work.

The filter I use is like this: From doesn't contain @ If that line is blank it will not have the @ symbol, but otherwise it will have that symbol, since every email address has it. You could do the same for the Sender line.

Almost forgot ... Here is what my filter looks like why I try building it:

Trying to fight spam with static filters is pretty much hopeless. Use junk mail controls for this. http://kb.mozillazine.org/Junk_Mail_Controls

Thanks but I do of course use Junk Mail Controls already. That's quite different than this issue. I's not learned behavior I'm looking for. I want to delete ANY message that does not contain a sender address. That'sa filter issue.
