The mailing lists server migration is now complete - Mailman is now running on server sodium.

As some people pointed out, my message earlier today was indeed sent out with the wrong Date header. I simply redirected my old mail and edited it a bit, forgetting that the Date header would not be adjusted by my mail client. Sorry for that. :)

The Mailman migration went smoothly, and I'm not aware of any problems. Please let us know in Bugzilla or on IRC (#wikimedia-tech) if you're experiencing any new issues.

Unfortunately we needed to change the IP address of lists.wikimedia.org for this migration. Some large e-mail providers (e.g. Google) are rate limiting reception of mail messages from the new IP (208.80.154.4) because it's not known and whitelisted yet. To prevent further mail delivery delays today, I've configured the new lists server to forward mails that would otherwise be delayed via the old mail server and old source IP address again, for the time being.

Thanks,
