The projects of the Wikimedia Foundation have a number of mailing lists which are open to anyone who subscribes and a few private mailing lists open only to selected users.
Please see the list descriptions for posting information. Most lists are moderated, so that posts by non-members need to be manually approved. Some lists disallow any posts by nonmembers.
Please respect Wikiquette and avoid personal attacks on the mailing lists, especially in the subject header as this is likely to be repeated by those replying. File a request at Phabricator for problems with mailing lists or for starting a new list.
Mailing lists are available in a number of formats: via a web archive, by email, or by NNTP using the mail-to-news gateway Gmane. Offsite archives of Wikipedia's mailing lists can be found at Gmane, MARC, Gossamer Threads, and Nabble Forums.
Email addresses are currently obfuscated in the downloadable archives, making them unreadable by some mail readers. To convert one of these archives to mbox format, you could use perl -p -i -e '/^From/ && s/ at /@/' filenameorsed '/^From /s/ at /@/' obfuscated.mbox > clear.mbox.
Wikipedia-l for issues specific to Wikipedia (and not sister projects such as Wiktionary) but affecting editions of Wikipedia in more than one language
There are various private mailing lists hosted by Wikimedia Foundation servers, although some of them allow public messaging. They facilitate internal communication among Wikimedia Foundation board members, and certain committees and subcommittees.
oversight-l, the oversight mailing list, used for oversighter group discussion only (only those with oversight rights can send to or read it, non-member emails are automatically rejected) NOTE:Please do not send requests for oversight to this list any longer. Instead, use oversight-en-wp mentioned below.
oversight-en-wpwikipedia.org, the oversight request VRT queue (anyone can send messages and requests to this address, but only users with oversight rights can view those messages).
checkuser-l, the global checkuser mailing list (only those with checkuser rights can send to or read it, non-member emails are automatically rejected)
