Thanks, Thomas.  Indeed, if I try this:

set from="undisclosed sender:;"

I get:

        From: Michael Elkins <undisclosed sender>:

Which is obviously wrong.  However, the proposed standard says 
user agents SHOULD NOT allow the use of groups except when 
"necesary" (presumably in the context of EAI)
