Weiterlesen.- Try to set on main setting a sender address with the same domain of your blog: sebesta-seklit.net (you are using t.sebesta@sebesta.at)
but at first: I have no sender adress on the same domain and
second: Die vorhergehenden Newsletter wurden problemlos versandt bis gestern
I think I have adjusted something in the configuration and did not notice it and do not find it now?
