As implied by Boyd in a sibling post, the package 'exim4' is what's
termed a metapackage, a package whose only role is to pull in other
packages via Depends. The package management toolchain doesn't assume
you also want to purge the packages exim4 depends on. As It Should Be,
IMHO.

You can see this easily if you have package 'debtags' installed. In the
description pane, you can see the package tags, one of which is
role::metapackage.

Probably the most succinct definition is in aptitude, actually. Start a
new debtags browser view, and select role::metapackage.

One of the References should have more information. I don't remember if
it's the user or developer reference though -- no net access as I write
this mail.
