A critical incompatibility between the Mailman 2.1.18 final release and Python versions older than 2.6.5 or thereabouts affecting the DMARC Wrap Message action was discovered and fixed. This incompatibility also existed in the 2.1.16 and 2.1.17 releases.

Thus, I have released Mailman 2.1.18-1 with a fix for this incompatibility. Please use 2.1.18-1 and not 2.1.18.

These releases have new features to help with mitigation of the impacts of DMARC on mailing lists as well as fixing several bugs.

Python 2.4 is the minimum supported, but Python 2.7 is recommended.

There are significant new i18n strings associated with the DMARC mitigation features. If you are interested in helping with the translations of these strings, see <http://wiki.list.org/x/MQ>.

There is also a new dependency associated with these features. Namely, the new Privacy options -> Sender filters -> dmarc_moderation_action feature requires that the dnspython <http://www.dnspython.org/> package be available in Python.

See the attached README 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.
