Where does your commune host email? I did an analysis via DNS records and plotted it on a map:

This is an early version, looking for feedback 👀

@davidhuser A lot of them have spf.protection.outlook.com in their SPF which means that there is a high probability that the mailboxes are actually hosted on M365 but they use a (cloud-hosted) mail security gateway like SEPPMail or cleanmail et al.
I just checked some and the map should be a lot more red IMHO.

@faebudo I believe to have fixed these issues on https://mxmap.ch by introducing a confidence score instead of binary classification
