It is no joke, there really are two users who deleted all their email.
 I'd assume they were more accustomed to the paged view in
traditional, also used in free webmail interfaces.  It is rather
alarming if you don't think this is a serious issue.

We had used a trash in the past with cyrus and imp 3, and people would
fill up their quota with deleted mail they didn't know was there.

How do I enable the trash?  Is this the same as Virtual Trash? I found
a checkbox to "Automatically create special mailboxes" in a UI part of
config and turned this on.  Deleted messages are not copied into my
trash.

Also, does it have a way to automatically delete from trash after XX
number of days?
