The subscriber which has subscribed to this list using a Microsoft mailbox (@live.ru?) is still subscribed, and still has that mailbox set to forward e-mails to a Gmail address.
Which would be fine, except Microsoft also still hasn't fixed the way their servers do forwarding, meaning today I got another "undeliverable" error message relayed to me from postmas...@outlook.com with mx.google.com's complaint about how Microsoft didn't set the correct "Envelope-From" when forwarding the message... -- Nuno Silva
