I just recently moved my outset.ws domain to Zeit name servers. That's my 13 years old domain which I'm not using it anymore. It makes sense to point to krasimirtsonev.com. The thing is that I have an email which is used all over the net. I of course want to keep that email. And suddenly I wasn't able to receive messages to it. I started missing some very important emails. Like bills that have to be paid and GitHub notifications.

Sometimes the uploading of crossdomain.xml file is not enough to get the things working.
