About Postfach

Postfach

We run no servers, so there is nothing of yours on one

We run no servers, so there is nothing of yours on one. A call from our hosting provider started it. They asked whether one of our important addresses had anything to do with a big cloud company — it didn't. It turned out the mail app we were using was routing through that company to deliver push notifications.
