+The checks should ensure that configuration changes to exim didn't break
+anything.
+
+Several types of checks should be performed:
+
+* ROUTING
+* ACCESS
+* AUTHENTICATION
+
+
+Which parameters do we need to set for checking?
+Which parameters influence Routing, Access Control and Authentication?
+
+First we could focus on simple -bt or -bv checks. But this does not
+suffice, since even routing could depend on source IP, sender address
+and so on.
