Unknown email address in my iCloud backup

I have just noticed that my iCloud backup did not work for the last three days on my iPhone 4, iOS 6.1.2 When I started to look arround I found in Settings> iCloud> Account> Advanced> Mail that exept my @icloud.com and @me.com there is two unknown email addresses. makaro...@icloud.com and makaro...@me.com.

I made a reset of the phone from iTunes, but the unknown email addresses is still there.

Does anybody know whats going on here 😕

(The phone don't have jailbreak.)
