My domain got deactivated

Apparently radix.website, the registry for the tld .space deactivated my domain because of a spam report. Now I really would like to know what happened. I have only one server which sends out mails and this server is not an open relay, has only a couple of users and each one with a unique and complex password. Thus I doubt they got phished. Other servers have mailing-software running but not exposed to the outside. And the mail-server is an OpenBSD-server that gets all the updates asap (it is already on 6.3 which got released yesterday). So I have no idea what happened there. And that they deactivated the whole domain because of the spam-report means for me that I will get rid of it and need to get something from a more sane registrar. Luckily I have a different domain for my servers than for my public stuff. Thus I could reconfigured the domain of my mail-server and was able to receive and send mail again. This all happened btw on the night from Maundy Thursday to Good Friday. So I only noticed it pretty late and get bad support times. In addition the Whois-entry still works and the delegated nameservers have the correct entries. My service provider wasn’t notified at all. So it was hard to figure out what happened to my domain.
