I can look into revising the script to use the mailbox.UnixMailbox class
instead. which will work with python 2.4.

Note that I run a production CentOS 5 server on which I have installed
Python 2.6.5 from source. The default Python on this server is still
2.4.3 as changing the default breaks yum and possibly other things, but
I use python2.6 for things I install from source like Mailman, bzr and
mod_wsgi.

It should work with Python 2.5. I will either fix the script to work
with Python 2.4 or add a "requires at least Python 2.5" note to it.
