When setting up new machinees

Speaking of the Exim install; the latest Computing Service friendly probe has detected a listening Exim mail service on tiree. It is a University policy that unregsitered mail servers are not allowed. Please can you make sure that Exim is only being run on tiree as a local relay client and not as a listening daemon. The easiest way to do this is make sure that it is not invoked with the -bd option. If you need any pointers on how to configure Exim 3 as a client only, please feel free to have a look at the /etc/exim.conf file on any of the appc systems.
