To start with - I have for several days looked for a post describing my problem, but without any luck
The issue: All () incoming emails ending up in the Spam folder
My MIAB was installed a few weeks ago on a VPS. The installation went without any apparent issues and it was initially functioning as expected. I have since upgraded MIAB, as an update was available in the admin panel.
For about a week now i noticed that I stopped receiving emails and that all had gone to the Spam folder. Emails from Google and Microsoft, and even emails from myself and my server notifications.
Here is the redacted source from one

All is green in the MIAB admin panel.
My score is 10/10 on mail-tester.com as well as on mxtoolbox.com
I have whitelisted in /etc/mail/spamassassin/local.cf
All caught emails have a spam score between -2 and 3
Where should I start looking?
Does anyone recognise/have experienced this behaviour?
