[Zope] External script question

I sincerely appreciate your help with this.  I am in a bit of a permissions
quandary I think -- perhaps you can help me out.  Using your code below, the
following error was returned:

  File "/home/mailman/Mailman/Utils.py", line 265, in MakeDirTree
    os.mkdir(made_part, perms)
OSError: [Errno 13] Permission denied: '/home/mailman/lists/test'

The code was trying to create the directory 'test' in the
/home/mailman/lists/ directory.  The 'list' directory has the following
permissions and listing:

drwxrwsr-x    2 mailman mailman      4096  Jun 24 15:21 lists

I added user zope to the mailman group, but this still had no effect.  I
guess I'm having a difficult time understanding why I can run this when
logged in as "zope" from the shell, but not from the ZMI (where I have used
a script to verify the username is 'zope').

Any additional ideas?

IMHO you should carefully check the os.system() call's return value.

you could replace the os.system() call with the following one
which I know for sure works :

def myexec(commandline) :
    import popen2
    process = popen2.Popen3(commandline, capturestderr=1)
    retcode = process.wait()
    output = process.fromchild.read()
    errors = process.childerr.read()

and check retcode according to the W* functions in

of course depending on the retcode you may or may not have
to read the child's stdout or stderr.
