More Info for Email Admins

Status code: 550 5.7.193 The Microsoft 365 group, info@haw-hamburg.de, is configured to reject messages sent to it from outside its organization -- unless the sender is a guest group member. stapf@zapf.in isn't part of the organization, and it isn't a guest group member.
