Is it possible to have a Trashbox?

[James Power]

Hi,

I'm new to mutt and wonder if there's a way for mutt to 
set up a trashbox. That is to say, whenever I delete a
mail, it go into the trashbox; the "garbage" in the trashbox
will be emptyed on demand or periodically.

Any hint will be appreciated.
