What I would like is to have any option in the
virtual folders to say "If sender is a member of
this address book".  Basically allow any of the
addresses in that book to have the message put in
the folder.

For example.  I currently have a virtual folder
for messages from my family.  So I have that
virtual folder set up to have messages in it from
my brother, mother, father, etc.  I also have an
address book of addresses of my family.  Currently
I have to keep these in sync manually.
