Unfortunately, that doesn't work. apt immediately bombs out with "E:
Internal Error, Couldn't configure a pre-depend", while installing all
three packages using dpkg simultaneously doesn't work as well:

Looks like we have the following problem:
- exim4-daemon-light and exim4-base are to be installed
- exim4-daemon-light is not unpacked because it pre-depends on
exim4-base.
- exim4-base can not be configured because exim4-daemon-light is not
yet unpacked.
This seems like the clash cannot be solved. Or does anybody have any
ideas?
Do I see correctly that the default MTA is selected by means of
package priority, like that the only MTA of Priority: Important is the
default? Is there any other means of selecting the default MTA?
And do I see correctly that the rule "Packages must not depend on
packages with lower priorities" is a legacy from the times where CD
makers were not able to follow Dependency chains?
