Something broke the init system of mail.eskimo.com such that necessary things are not being started on the client mail server when it boots.  No cron jobs ran for some period of time and this caused the anti-virus database not to get updated.  This would have made it possible for a virus to propagate from one infected customers computer to another.  Mail may be interrupted for short intervals as I will need to perform a number of reboots to test and get the start-up logic straightened out.
