Zurich uses MS 365

Hi

Thanks for creating that awesome map.

I'm pretty sure Zurich uses MS 365, but I can't verify it. AOZ, which is a Stadt Zurich Organisation, shares the IT department and even has the same MX records as zuerich.ch, sends out e-mails with ....outbound.protection.outlook.com in the headers.

Cheers,
Adi

Can't verify it either, but they definitely do not use Hostpoint in their MX.

~ % dig mx zuerich.ch +short
10 mx3.stadt-zuerich.ch.
50 mx4.stadt-zuerich.ch.

I don't see any 365 in their SPF tree either

hi, bigger cities are trickier, I think they use MS but it's not reflected as such yet. Their domain is stadt-zuerich.ch as I was informed by someone.

That domain doesn't handle email, from what I can tell, zuerich.ch is the one they use for email.

zuerich-ch.mail.protection.outlook.com exists and has A and AAAA address records, which is a clear sign zuerich.ch uses MS 365. I think the same mapping scheme is used for many other domains, it would be interesting to test this for all the municipalities.

Next step could be to test if this host accepts emails to a @zuerich.ch email address (I have not tested this yet), but that means you would have to know a valid email adress for every municipality if you want to also test this everywhere.
