Hi Benoît, All I see from @bounce.email.nzz.ch comes from mta.email.nzz.ch [13.111.14.63].
Interestingly, I see a lot of temp rejects in our logs on 17. August (between 16:40 and 19:26) from that domain and IP because we were not able to resolve the domain. Mails are still coming up to today at the same rate as earlier. Hope this helps.
