I am happy to announce the first release candidate for the 2.1.14 release of the 2.1 stable maintenance branch of GNU Mailman.
Mailman 2.1.14rc1 is mainly a bug fix release, but it contains one security fix as previously announced at http://mail.python.org/pipermail/mailman-announce/2010-September/000151.html and one new feature.
This new feature controls the addition/replacement of the Sender: header in outgoing mail. This allows a list owner to set include_sender_header on the list's General Options page in the admin GUI. The default for this setting is Yes which preserves the prior behavior of removing any pre-existing Sender: and setting it to the list's -bounces address. Setting this to No stops Mailman from adding or modifying the Sender: at all.
Additionally, there is a new Defaults.py/mm_cfg.py setting ALLOW_SENDER_OVERRIDES which defaults to Yes but which can be set to No to remove the include_sender_header setting from General Options, and thus preserve the prior behavior completely.
Python 2.4 is the minimum supported, but Python 2.5.or 2.6 is recommended.
See the changelog at https://launchpad.net/mailman/2.1/2.1.14rc1 for more details.
Mailman is free software for managing email mailing lists and e-newsletters. Mailman is used for all the python.org and SourceForge.net mailing lists, as well as at hundreds of other sites.
