How is domain_taxonomy_access module configured? I am trying to use the domain_taxonomy_access module, but I do not know how it is configured.

How I do so that the user of a certain domain can manage their newsletters?

I am trying to implement the solution shown here: https://www.drupal.org/project/domain/issues/558692

Thanks
I have found the solution by myself.

I use domain access with simplenews, i need the Domain Simplenews to,  

What you have to do, is go to:

structure / taxonomy / [yourtaxonomynewsletter]


Then edit some term of the taxonomy and at the end of the configuration called Term source domain there is an option to set the domain to the taxonomy.
