Mailman is available from the following sources: Note: the GNU ftp site may lag behind Launchpad, especially just after a release announcement. It often takes a little while for the GNU ftp site to catch up.

Signing keys

We always sign releases with the GPG keys of one of the core developers: Barry Warsaw, Mark Sapiro, or Tokio Kikuchi. Our public keys are available from all the public keyservers. For cross referencing, here are the keys we use to sign releases:
