Check the email settings on ACP under General Admin > Settings.
There might be missing something or the config is wrong...

I didn't change anything that just starts to happend when I try to register a new user.
I manage to solve for now, but this happend often.

Ask your provider for changes on the smtp server. Maybe you must change the passwort and user settings for it...
