This is the best solution, to my mind, as it has the extreme benefit of 
doing what makes the most sense to the enduser.  In other words, I 
receive a message today and move it to Trash immediately.  My sysadmin 
has helpfully told me that messages older than 7 days will be deleted 
from Trash.  The act of copying it to Trash starts the clock running. 
Moving the file out of Trash and back in the next day restarts the 
clock.  Anything that messes with INTERNALDATE will inevitably be wrong 
for the indecisive user.

I was going to argue for option #2, but then I realized that if I sit on 
a message for weeks and then Trash it, it would make more sense that it 
would be deleted 7 days hence, not that night.  Sites running without 
indexes shouldn't use this feature (or possibly this feature should be 
disabled if the appropriate index doesn't exist).
