Mailman 2.1.11 final released

I am happy to announce the final release of the Mailman 2.1.11.

Mailman 2.1.11 is a cleanup of a few problems found since the release of Mailman 2.1.10. It fixes the issue of shunted email subscribe requests and a few minor issues. It updates the contrib/mmdsr script for some 2.1.10 and 2.1.11 log and error messages, and it adds a new cron to cull and optionally archive old entries in the 'bad' and 'shunt' queues.

Mailman 2.1.11 has updates to several i18n translations.

A few bounce log messages now have the list name prepended.

There is a new| setting ACCEPTABLE_LISTNAME_CHARACTERS with default value '[-+_.=a-z0-9]'. This Python regular expression character class specifies the characters allowed in list names. The motivation for this is the fact that previously, a list named, e.g., xxx&yyy could be created and MTA aliases generated that would cause the MTA to execute yyy as a command. There is a possible security issue here, but it is not believed to be exploitable in any meaningful way.

If anyone is concerned about the security issue and not ready to upgrade, the mailman-2.1.11-listname-patch file contains a patch that can be applied to Mailman 2.1.9 or 2.1.10 to add this feature.

See the release notes at <> for more details.
