Internationalization

Mailman 2.1 is fully internationalized. This means you can add translations of all the email and web templates so that your users can interact with your mailing lists in their native language. Internationalization is handled as follows:

Each Mailman installation has a server default language. Mailman ships with US English as the server default.
Mailman comes with many supported languages, and if your language is on that list, it will just work.
Individual list owners can choose which languages they'd like their mailing list to support from the suite of site-enabled languages. The list owner can also select the list's default language. Mailing lists can thus be monolingual (with English or any other installed language as the default), or they can be multilingual.
Individual users can choose what their preferred language is, from the set of list-enabled languages. Thus, if a list is multilingual, the user can choose which language they'd prefer when interacting with Mailman.

It must be noted that Mailman never actually translates the messages that flow through its mailing lists. It's up to the list members to adhere to their community's language conventions.

Mailman Language Champions

Each language translation has a champion who coordinates updates and submits them to the Mailman project. If the language you are interested is listed here, please contact the champion for details. If your language is not listed here, or if you have general questions about I18N Mailman, please contact the mailman-i18n@python.org mailing list.

We are investigating using the Translation Project for future language support.
