[Mailman-Users] Setting sitewide defaults that can't be changed?

[Mike Alberghini]

I'm the admin of a Mailman server that is quickly running out of disk space.
One of the solutions our fearless leader wants to implement is a sitewide 
limit on message size.  I know I can set a default limit in mm_cfg.py, but
the list owners can always change that.  Is there a way to lock certain
settings so that they cannot be changed by anyone except the site admin?
