The "[Python-modules-team]" thing in the subject is probably enough to break the DKIM signature. We should really not be sending messages having broken signatures to the outside world, including our own email inboxes. And email users subscribed to one or more mailing lists should really use email filters to filter email, not rely on this obnoxious subject munging. More to the point, when you subscribe to a mailing list, you should be ready to accept all messages from such mailing list, not accept some messages and reject others. Thanks.
