I just visited the GM Fastlane blog, in order to find a contact address (I wanted to interview the team for the Community Guy podcast). I found an email address (for the GM Communications Directory), and dropped a note.
This was the reply I got…

recipients. This is a permanent error. The following address(es) failed:firstname.lastname@example.org

Not a good message to send GM.
