Cannot create info@ email

Hi,

It seems that for some reason I cannot create an account info@tbchellas.gr. During the initial setup it didn't accept it and I had to create an admin@tbchellas.gr instead. All other names are accepted except from info@tbchellas.gr, for which it says that it already exists even though I can't see it in the list with my other emails.

Is there any chance that It created an entry in your database and now it prevents me from creating it?

Thanks!
