Doesn't work (as I discovered the other day). The sender on this virus is
<> not hahaha@???. That's just the contents of the From: header.

The above code is the correct way to deal with this. Or you can use the
generic windows executable content filter and re-arranges the part that
drops null sender messages out of the filter befire the other checks.
