Investigating - When performing an OS upgrading on mailman (lists) last night we found a hidden unsupported dependency. No email has been lost, but it's queueing up. We'll be stopping the service, collecting the spooled emails, reverting to the old OS, and dropping the mail back in the queue for processing. This may take a few hours.
