This is almost trivial.
Modify the file ~mailman/Mailman/Utils.py
The first defined function therein is "list_exists" which is used when
creating a new list to determine if the list can be created.
"""Return true iff list `listname' exists."""
# The existance of any of the following file proves the list exists
# <wink>: config.pck, config.pck.last, config.db, config.db.last
# The former two are for 2.1alpha3 and beyond, while the latter
# two are for all earlier versions.
basepath = Site.get_listpath(listname)
for ext in ('.pck', '.pck.last', '.db', '.db.last'):
dbfile = os.path.join(basepath, 'config' + ext)
You could simply add your restrictions in here (but be sure to read up
on how Regular Expressions work in Python - they are different than what
your used to in shell expansions)...
Alternately, as the code points out, you could simply create a
directory under ~mailman/lists/ and then "touch config.db" in that
Viola! Now no user can create a list called "postmaster".
