Outlook 2003 Rules question

[Charley Kyd]

In Outlook 2003, Rules and Alerts, I'm wanting to use the "with selected
properties of documents or forms" option. This option allows us to define
selection criteria for a list of fields. The list box does not have the
**From** field. It does have Author and Last Author. Which of these, if any,
is the From field?

The reason I want to use this option is that it's the only one I've found
that allows me to select on information **not** in a field.

Thanks.
