Great suggestion, Vanguard! I ran Outlook with /SAFE and unfortunately, it
appears that Outlook is ignoring the "no automatic filtering" selection in
the Junk email options window.

When the first spam arrived, I got this pop-up:

"Outlook has downloaded a message that appears to be junk email. This
message was automatically moved to the junk folder."

So, now I'm at my wit's end. It seems that there is no way to tell Outlook
not to apply its own spam filtering rules. And, in fact, I DO want it to
apply its rules... but only after my rules are applied.

Have you sny further thoughts?
