Thanks for the snippet! However, I find the actions a bit strange:

This is ok.

This is strange, when the alternatives linkgroup has been set to manual
the readline would stay unaltered and the script would enter the clause.
However, as sendmail.exim already has been deleted in preuninstall
an error would have been thrown. Strange.
