I'm using IMP4 (previous version), so this may have changed somewhat.  in 
imp/config/prefs.php I see:

// use Virtual Trash folder
$_prefs['use_vtrash'] = array(
     'value' => 0,
     'locked' => false,
     'shared' => false,
     'type' => 'implicit');

I guess that was combined with Virtual Inbox in IMP5.

When I can't figure out how to set a value on these, I will change the 
value using the IMP interface, then go look at the value stored in the 
database backend.  You should see the serialized array value, which you 
can use on the vfolder value setting.

I'm sorry, I don't know if Virtual Trash is purged the same as traditional 
Trash folders.  Play around and find out!  :)
