I can't point to a Usermin-specific solution, but this is exactly what I 
did with a similar problem for some users trying to delete spam via one 
of our webmail systems.  Rather than having the user's Trash mail folder 
owned by that user, I changed the ownership of that file to "nobody". 
That way, deletes can succeed because the IMAP action of copying a 
messge to the Trash folder on deletion didn't increase their disk usage. 
  I also set up a cron job to periodically trim everyone's Trash folder, 
in much the same way I had set spam folders to be kept somewhat under 
control.

I've posted versions of the mail management scripts I wrote:

http://www.deepnet.cx/~kdeugau/spamtools/

Note that all of these scripts work on *nix mbox-format mailboxes;  it 
should be relatively simple to adapt them to maildir mailboxes.

Cron entries for most of them look like this:

# Spam expiry, automagical trash emptying, and quota warnings.
03 1 * * * root /root/autotrimtrash.pl
30 1 * * * root /root/custom-spam
30 2 * * * root /root/autoexpirespam.pl 25
45 3 * * * root /root/space_warn.pl
