There was no Problem with the license itself.
Everybody can publish a module under a 'all rights reserved'-License.
To use such a module, a written and signed permission is mandatory. Without it's not possible to install it.
It's a question of actual law only.
Sure, in forum you told that everybody can use the module. But it was a 'all rights reserved' and you do not explain precisely which of the reserved rights you gave for free. On other hand, why 'all rights reserved' if you negate your own license in next sentence?
So this is an absolutely unsafe legal situation. Nobody have a guaranty, that next month it's still allowed to use this module for free. A simple forum post is not a valid document to prove your permission later if necessary.
Unfortunately the right is not what we think with our common sense, what right shall be. The right has it's own life, own language, own meaning.
I hope you will understand now, why we can't accept '' 'all rights reserved' but you can use it as you want".
