Thanks, Mark.  I hadn't thought of the "from:" being embedded in the 
Subject: header.  And your RE correction makes perfect sense once I 
see it. ;-)

I'm pretty sure I don't have access to 'mm.config.[anything]' so I 
assume it's the default value.  Odds are, it was my imperfect RE that 
was keeping if from tripping.

Thanks All,
