Public domain would mean you can do anything you want with it. You
can't; in particular, you are not allowed to distribute derivative
works other than precompiled var-qmail packages without Dan's
permission.

If you download some source code and there is no license, you can't
assume that the source is in the public domain or that you have
permission to do anything covered by the exclusive rights given under
copyright law.
As it turns out, there is a license among Dan's web pages. See:
