I run a mailman3 instance with mainly private lists for which I know and trust every single member. Some of them have Hotmail email addresses, and the messages they send though our lists are rejected as being spam by most of the recipients' mail servers, while these are legitimate emails.
I'd welcome any pointer to best practices / howtos regarding mailman3 / exim4 configuration to mitigate this problem.
What does the non-delivery long entries say are the reasons for the rejections? Do you have a SPF record setup for your list domain? Do you have DMARC mitigation enabled for your list?
