email of bugzilla of opensuse

I am receiving my bugzilla reply mail on a historical freenet account that recently does not work well anymore (freenet causes me dns problems, no idea why). I tried to change the email to this one (disroot) but no luck up to now, even in my account settings no way to change the original historical email to something valid and new. Does anybody know a procedure to have this done? I have seen not further indication.
