Deleted messages are not gone until compacting occurs.  I think there is a greater responsibility to the user to actually remove what they think is gone.  While the concept of compaction (perhaps it needs a new name) is about incomprehensible to users and explaining it leaves them thinking about Zip for some reason.  They do expect their deleted mail to be gone when they empty the trash.

Personally I do not see the point of effort on compaction.  I think efforts would be better spent on the mbox replacement.  Then compaction can be consigned to the darkness of history.
