I'm including mailman-developers on this message, because I want to
discuss the issue of which Python versions to support.

My recommendation would be to run at least Python 2.4. Mailman 2.1.9
should run on Python 2.5, but earlier versions of Mailman won't.
While we still claim to be able to run Mailman 2.1 on versions of
Python back to 2.1, I believe we broke that claim in Mailman 2.1.9.
Does anybody care?
I would dearly love to drop support for Python 2.1 and Python 2.2
even in the Mailman 2.1 series. As I'm developing on OSX myself
these days, I can't even build these earlier versions of Python and
they haven't been supported by the PSF for years. In fact, Python
2.3 is no longer supported and I would even love to drop support for
Python 2.3 in Mailman 2.1.x, although I know we can't.
Then there is the question of what versions we support for Mailman
2.2, which is currently under development. Previously we've said
we'll support Python 2.3 but I think we should revisit that decision.
In summary my preferences would be:
Mailman 2.1.x supported on Python 2.3, 2.4, and 2.5. Drop support
for Python 2.1 and 2.2. We've done this accidentally in Mailman
2.1.9, so let's make it official.
Mailman 2.2 supported on Python 2.4 and 2.5.
