+ exim4 configuration.  The original setup is in /etc/exim4/exim-ldap-server-v4.conf, but it is easier to adjust the default exim4 setup than to edit the preloaded setup.
+ 
+ Setting this up consist of these steps:
+ 
+  1. Prepare the default exim4 config to use LDAP for user information.
+  1. Decide which DNS domain to use for public email (using example.com).
+  1. Set up the exim4 configuration with the new DNS domain
+  1. Change mail name for tjener to get valid addresses in outgoing email.
+  1. Switch to generated contiguration instead of the Debian Edu provided configuration.
+  1. Add port forwarding in the gateway, allowing connections from the outside for port 25 to make it to tjener.intern
+  1. Update DNS, add MX entry for the selected DNS domain.
